Add Template to deploy forgejo.

This template allows deploying a forgejo en either Scaleway or Hetzner
(untested) without much knowledge about them.
It DOES require knowledge about Terragrunt and ansible. A wizard of
sorts is provided but it will not guarantee success without some
knowledge about the underlying technology.
