[GITEA] Skip unsupported code comment
- If there's a code comment that's received during the migration that
contains no diffhunk, skip it. This either means it was commenting on
old diffhunk or it's just a general codecomment. Forgejo supports
neither of such type of code comment.
- Resolves https://codeberg.org/forgejo/forgejo/issues/1407
