build: remove dependency on @types/chokidar (#35371)

We recently updated chokidar to `3.0.0`. The latest version of
chokidar provides TypeScript types on its own and makes the extra
dependency on the `@types` unnecessary.

This seems to have caused the `build-packages-dist` script to fail with
an error like:

```
[strictDeps] transitive dependency on external/npm/node_modules/chokidar/types/index.d.ts
   not allowed. Please add the BUILD target to your rule's deps.
```

It's unclear why that happens, but a reasonable theory would be that
the TS compilation accidentally picked up the types from `chokidar`
instead of `@types/chokidar`, and the strict deps `@bazel/typescript`
check reported this as issue because it's not an explicit target dependency.
