Andrew Scott 8a56c99f87 docs(router): Update router guide to use UrlTree for guard redirects (#37100)
The current implementation for redirecting users inside guards was in place
before the feature was added to allow `CanActivate` and `CanActivateChild` guards
to return `UrlTree` for redirecting users.

Returning `UrlTree` should be the default method, as it provides a more desirable
redirecting experience. When using `router.navigate` followed by `return false`,
the `Router` calls `resetUrlToCurrentUrlTree` (in the `finalize` operator) before
processing the navigation to the new route.  This can result in an undesirable
history if the navigation was the first navigation in the application - that is,
the route will briefly be reset to just `/` (see #36187).

Fixes #36187
