feat(gh_actions_ls): allow .forgejo and .gitea as root_dir

[Crashdummyy]

The projects forgejo and gitea share the same syntax even across the composite actions.
There are only negligible differences IMHO which besides the actions author should be aware of.
Besides its only a matter of time until those become implemented as well.

It'd be a nice addition to let it attach for those systems as well

seems fine but should be called out in the docs
