This is required as e.g. `token` from `@Inject` is
accessed in string form via makeParamDecorator
but as a property in the `ReflectiveInjector`.
Closes#16889 as this is a more general fix.
* docs(animations): fix links to `Component` animations
* docs(core): fix links to `ReflectiveInjector` methods
The `resolve` and other methods were moved from the
`Injector` to the `ReflectiveInjector`.
* docs(core): fix links to `Renderer`
The local links were assuming that that methods were on the
current document (e.g. `RootRenderer`), but they are actually
on the `Renderer` class.
* docs(router): fix links to methods
* docs(forms): fix links to methods
* docs(core): fix links to methods
* docs(router): fix API page links and an internal link
