build(docs-infra): use pinned dependencies when possible in ng-packages-installer (#28510)

Previously, `ng-packages-installer` would replace the version ranges for
all dependencies that were peer dependencies of an Angular package with
the version range used in the Angular package. This effectively meant
that the pinned version (from `yarn.lock`) for that dependency was
ignored (even if the pinned version satisfied the new version range).

This commit reduces non-determinism in CI jobs using the locally built
Angular packages by always using pinned versions of dependencies for
Angular package peer dependencies if possible.

For example, assuming the following versions for the RxJS dependency:

- **aio/package.json**: `rxjs: ^6.3.0`
- **aio/yarn.lock**: `rxjs@^6.3.0: 6.3.3`
- **@angular/core#peerDependencies**: `rxjs: ^6.0.0`

...the following versions would be used with `ng-packages-installer`:

- Before this commit:
  - **aio/package.json**: `rxjs: ^6.0.0`
  - **node_modules/rxjs/**: `6.4.0` (latest version satisfying `^6.0.0`)
- After this commit:
  - **aio/package.json**: `rxjs: ^6.3.0`
  - **node_modules/rxjs/**: `6.3.3` (because it satisfies `^6.0.0`)

 ## Using ServiceWorker locally
 
-Since abb36e3cb, running `yarn start --prod` will no longer set up the ServiceWorker, which
-would require manually running `yarn sw-manifest` and `yarn sw-copy` (something that is not possible
-with webpack serving the files from memory).
-
-If you want to test ServiceWorker locally, you can use `yarn build` and serve the files in `dist/`
-with `yarn http-server dist -p 4200`.

-For more details see #16745.

+ServiceWorker. If you want to test the ServiceWorker locally, you can use `yarn build` and then

+## Developing the preview server TypeScript files
+
+If you are running Docker on OS/X then you can benefit from linking the built TypeScript
+files (i.e. `script-js/dist`) to the JavaScript files inside the Docker container.
+
+First start watching and building the TypeScript files (in the host):
+
+```bash
+yarn build-watch
+```
+
+Now build, start and attach to the Docker container. See "Setting up the VM"
+section in [TOC](_TOC.md). Then link the JavaScript folders (in the container):
+
+```bash
+aio-dev-mode
+```
+
+Now whenever you make changes to the TypeScript, it will be automatically built
+in the host, and the changes are automatically available in the container.
+You can then run the unit tests (in the container):
+
+```bash
+aio-verify-setup
+```
+
+Sometimes, the errors in the unit test log are not enough to tell you what went wrong.
+In that case you can also look at the log of the preview-server itself.
+A helper script that runs the unit tests (i.e. `aio-verify-setup`) and displays the
+last relevant test-preview-server log is:
+
+```bash
+aio-verify-setup-and-log

@@ -32,48 +33,35 @@ This section gives a brief summary of the several operations performed on CI and
 container:
 
 
-### On CI (Travis)
-- Build job completes successfully.
-- The CI script checks whether the build job was initiated by a PR against the angular/angular
-  master branch.
-- The CI script checks whether the PR has touched any files that might affect the angular.io app
-  (currently the `aio/` or `packages/` directories, ignoring spec files).
-- Optionally, the CI script can check whether the PR can be automatically verified (i.e. if the
-  author of the PR is a member of one of the whitelisted GitHub teams or the PR has the specified
-  "trusted PR" label).
-  **Note:**
-  For security reasons, the same checks will be performed on the server as well. This is an optional
-  step that can be used in case one wants to apply special logic depending on the outcome of the
-  pre-verification. For example:
-  1. One might want to deploy automatically verified PRs only. In that case, the pre-verification
-     helps avoid the wasted overhead associated with uploads that are going to be rejected (e.g.
-     building the artifacts, sending them to the server, running checks on the server, detecting the
-     reasons of deployment failure and whether to fail the build, etc).
-  2. One might want to apply additional logic (e.g. different tests) depending on whether the PR is

 ### Implementation details
 This section describes how each of the aforementioned sub-tasks is accomplished:
 
-1. **Verify which PR the uploaded artifacts correspond to.**
+1. **Receive notification from CircleCI of a completed build**
 
-   We are taking advantage of Travis' [JWT addon](https://docs.travis-ci.com/user/jwt). By sharing
-   a secret between Travis (which keeps it private but uses it to sign a JWT) and the server (which
-   uses it to verify the authenticity of the JWT), we can accomplish the following:
-   a. Verify that the upload request comes from Travis.
-   b. Determine the PR that these artifacts correspond to (since Travis puts that information into
-      the JWT, without the PR author being able to modify it).
+  CircleCI is configured to trigger a webhook on our preview-server whenever a build completes.
+  The payload contains the number of the build that completed.
 
-   _Note:_
-   _There are currently certain limitation in the implementation of the JWT addon._
-   _See the next section for more details._
+2. **Verify that the build is valid and can have a preview.**
 
-2. **Fetch the PR's metadata, including author and labels**.
+   We cannot trust that the data in the webhook trigger is authentic, so we only extract the build
+   number and then run a direct query against the CircleCI API to get hold of the real data for
+   the given build number.
 
-   Once we have securely associated the uploaded artifacts to a PR, we retrieve the PR's metadata -
+   We perform a number of preliminary checks:
+   - Was the webhook triggered by the designated CircleCI job (currently `aio_preview`)?
+   - Was the build successful?
+   - Are the associated GitHub organisation and repository what we expect (e.g. `angular/angular`)?
+   - Has the PR touched any files that might affect the angular.io app (currently the `aio/` or
+     `packages/` directories, ignoring spec files)?
+
+   If any of the preliminary checks fails, the process is aborted and not preview is generated.
+
+3. **Download the build artifact.**
+
+   Next we make another call to the CircleCI API to get a list of the URLs for artifacts of that
+   build. If there is one that matches the configured artifact path, we download the contents of the
+   build artifact and store it in a local folder. This download has a maximum size limit to prevent
+   PRs from producing artifacts that are so large they would cause the preview server to crash.
+
+4. **Fetch the PR's metadata, including author and labels**.
+
+   Once we have securely downloaded the artifact for a build, we retrieve the PR's metadata -
    including the author's username and the labels - using the
    [GitHub API](https://developer.github.com/v3/).
    To avoid rate-limit restrictions, we use a Personal Access Token (issued by
    [@mary-poppins](https://github.com/mary-poppins)).

 ## Assumptions / Things to keep in mind
 
-- Each trusted PR author has full control over the content that is uploaded for their PRs. Part of
-  the security model relies on the trustworthiness of these authors.
+- Other than the initial webhook trigger, which provides a build number, all requests for data come
+  from the preview-server making requests to well defined API endpoints (e.g. CircleCI and Github).
+  This means that any secret access keys need only be stored on the preview-server and not on any of
+  the CI build infrastructure (e.g. CircleCI).
 
-- Adding the specified label on a PR and marking it as trusted, gives the author full control over
-  the content that is uploaded for the specific PR (e.g. by pushing more commits to it). The user
+- Each trusted PR author has full control over the content that is hosted as a preview for their
+  PRs. Part of the security model relies on the trustworthiness of these authors.
+
+- Adding the specified label on a PR to mark it as trusted, gives the author full control over the
+  content that is hosted for the specific PR preview (e.g. by pushing more commits to it). The user
   adding the label is responsible for ensuring that this control is not abused and that the PR is
   either closed (one way of another) or the access is revoked.
-
-- If anyone gets access to the `PREVIEW_DEPLOYMENT_TOKEN` (a.k.a. `NGBUILDS_IO_KEY` on
-  angular/angular) variable generated for each Travis job, they will be able to impersonate the
-  corresponding PR's author on the preview server for as long as the token is valid (currently 90
-  mins). Because of this, the value of the `PREVIEW_DEPLOYMENT_TOKEN` should not be made publicly
-  accessible (e.g. by printing it on the Travis job log).
-
-- Travis does only allow specific whitelisted property names to be used with the JWT addon. The only
-  known such property at the time is `SAUCE_ACCESS_KEY` (used for integration with SauceLabs). In
-  order to be able to actually use the JWT addon we had to name the encrypted variable
-  `SAUCE_ACCESS_KEY` (which we later re-assign to `NGBUILDS_IO_KEY`).
