[FEAT] add Forgero Git Service (squash) more tests

Previously only Gitea service was being tested under self-hosted migrations. Since Forgejo is also self-hosted and in fact use the same downloader/migrator we can add to this suite another test that will do the same, migrating the same repository under the same local instance but for the Forgejo service (represented by 9)
