It turns out that we don't document anywhere how ngc works and what options we support.
I added a brief section, without going too much into details because most users should not need to use ngc directly.
I also came across some bug in `ngc` and filed #42372.

The faq on `forRoot` implies that you cannot and should not call `forRoot` for an import
outside the AppModule. This is technically incorrect. This commit clarifies
the statement and refers the reader to the hierarchical injectors guide.

In #39176 Alan noted that schematics is currently misplaced and should really be under the Angular Tools menu item.
In that issue, Alan also noted the "Angular Compiler" and "Angular CLI" are not refereced from here.
Since the issue was created "Angular Compiler" has already been moved under "Angular Tools".
Angular CLI is documented throughout the docs, and the "CLI Command Reference" under References is really just a reference
so it seems correctly located.

A couple important things to note about the behavior:
* The component is destroyed, meaning that all of its members will be destroyed as well, including any subscriptions to the route params
* This _does not_ mean that any `finalize` operators or `complete` on the subscription is called. This only happens if the source completes or you unsubscribe from the subscription. The documentation doesn't state that the `Router` will do this, though I can still understand why the behavior is confusing.
You can play around with these scenarios here:
https://stackblitz.com/edit/rxjs-hmpizx
* `complete` the source without unsubscribe: `next`, `complete` and `finalize` are all called, even when `complete` is called before the `next` from the `delay`
* `unsubscribe` from subscription without `complete` on the source: `finalize` happens, but the `complete` of the subscription does not, and neither does `next`
So even if the `Router` were to call `complete` on all of the `Observables` on an `ActivatedRoute`, you would see that any subscriptions with a `delay` operator would still get called.

Correctly the reference to ng-for as `NgForOf` so that we get the word linked to the API page.
`NgFor` is not a JavaScript symbol so the docs infra doesn't autolink to the API page unless
we use the correct symbol name - `NgForOf`.

The latest SW app version knows that `/devtools` should be redirected to
`/guide/devtools`. However, if a user has an older app version installed
(and until the SW downloads the latest version) they will get a 404 when
navigating to `/devtools`.
The reason is that the SW will see `/devtools` as a regular navigation
URL and serve `index.html` instead. The Angular app will then try to get
the content for `/devtools` by fetching `/generated/docs/devtools.json`
(which does not exist).
This commit fixes the issue by redirecting
`/generated/docs/devtools.json` to
`/geenrated/docs/guide/devtools.json`. When a user visits `/devtools`
for the first time, they will still be able to see the guide content
(while the SW updates in the background). On subsequent visits (once the
SW has downloaded the latest app version), they will be redirected to
`/guide/devtools`).
At a later time, once we are confident that the majority of users will
have updated to a newer app version, we can remove this temporary
redirect.

This fixes an issue in part 5 of the Tour of Heroes tutorial on
angular.io. At the end of the `Add RouterOutlet` section, the reader navigates to
`"/heroes"`. The next section, `Add a navigation link`, instructs the user to click ona link on the dashboard page to navigate to the heroes page. This is problematic because the previous section instructed the reader to navigate to the heroes page, not the dashboard. It assumes, the reader is on the dashboard page.
Fixes issue by instructing the reader to navigate back to the dashboard
after navigating to `"/heroes"` in the `Add RouterOutlet` section.
