Matthias Kunnen b5551609fe fix(router): fragment can be null (#37336)
ActivatedRoute.fragment was typed as Observable<string> but could emit
both null and undefined due to incorrect non-null assertion. These
non-null assertions have been removed and fragment has been retyped to
string | null.

BREAKING CHANGE:
Strict null checks will report on fragment potentially being null.
Migration path: add null check.

Fixes #23894, fixes #34197.
