refactor(docs-infra): fix docs examples for Angular-specific tslint rules (#38143)

This commit updates the docs examples to be compatible with the
following Angular-specific tslint rules:
- `component-selector`
- `directive-selector`
- `no-conflicting-lifecycle`
- `no-host-metadata-property`
- `no-input-rename`
- `no-output-native`
- `no-output-rename`

This is in preparation of updating the docs examples `tslint.json` to
match the one generated for new Angular CLI apps in a future commit.
