[v10.0/forgejo] fix: return 404 for empty repositories (#7014)

Browse source 
**Backport:** https://codeberg.org/forgejo/forgejo/pulls/7003

Some endpoints (`/api/v1/repos/*/*/raw`, `/api/v1/repos/*/*/media`, ...;
anything that uses both `context.ReferencesGitRepo()` and
`context.RepoRefForAPI` really) returned a 500 when the repository was
completely empty. This resulted in some confusion in
https://github.com/datalad/datalad-usage-dashboard/issues/47 because the
same request for a non-existent file in a repository could sometimes
generate a 404 and sometimes a 500, depending on if the git repository
is initialized at all or not.

Returning a 404 seems more appropriate here, since this isn't an
unexpected internal error, but just another way of not finding the
requested data.
