fix(install): switch Forgejo Runner to gitea/act_runner from Docker Hub

code.forgejo.org/forgejo/runner does not have usable version tags.
Use gitea/act_runner:latest from Docker Hub which is fully compatible
with Forgejo Actions. Update register/daemon commands accordingly
(act_runner instead of forgejo-runner, --instance instead of --url).
