[GITEA] Add noreply email address as verified for SSH signed Git commits

- When someone really wants to avoid sharing their email, they could
configure git to use the noreply email for git commits. However if they
also wanted to use SSH signing, it would not show up as verified as the
noreply email address was technically not an activated email address for
the user.
- Add unit tests for the `ParseCommitWithSSHSignature` function.
- Resolves https://codeberg.org/Codeberg/Community/issues/946
