* More pleasantly handle broken or missing git repositories

In #17742 it was noted that there a completely invalid git repository underlying a
repo on gitea.com. This happened due to a problem during a migration however, it
is not beyond the realms of possibility that a corruption could occur to another
user.

This PR adds a check to RepoAssignment that will detect if a repository loading has
failed due to an absent git repository. It will then show a page suggesting the user
contacts the administrator or deletes the repository.

Fix #17742

* Update options/locale/locale_en-US.ini
