since this is no longer supported and we have a dedicated module for
forgejo for quite some time now.
Such warning is, however, becoming more and more important, since
forgejo is no longer a soft-fork of gitea, but rather a hard-fork.
And as such, it will slowly but surely no longer be a drop-in
replacement.
Additionally, I hope that this warning will prevent users from
reporting issues with forgejo to nixos/gitea maintainers.
The accompanying forgejo.md, from which the manual section is created,
will be updated over the next few weeks when forgejo officially
publishes their blog post about all this and the way forward, so we can
link to it.
