The `repo.SingleRelease` handler was broken by gitea#29149, as the switch to `getReleaseInfos` stopped returning tags without an associated release. This resulted in the web UI showing a 404 when trying to view a tag without a release. This restores the functionality by explicitly including tags in the search, and also adds tests to exercise the fix. Signed-off-by: Gergely Nagy <forgejo@gergo.csillger.hu>
