build(docs-infra): remove redundant `navigationUrls` globs from `ngsw-config.json` (#42452)

This commit removes some `navigationUrls` globs from `ngsw-config.json`
that have no effect. More specifically:
- It removes globs of the form `!/**/xyz.html`, since these are already
  covered by the more generic `!/**/*.*` glob.
- It removes `!/api/**/NgFor`, since it does not have a corresponding
  redirect rule in `firebase.json`.

This is in preparation of automatically generating the ServiceWorker
`navigationUrls` based on `firebase.json`.
