[BRANDING] add Forgejo Git Service and migration UI

[FEAT] add Forgejo Git Service (squash) register a Forgejo factory

newDownloader will fallback to a git service and not migrate issues
etc.

[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)
