* Feat: Use goreleaser

* Feat: Add docker build, remove goreleaser

* Fix: Add image name

* Feat: Use ghcr.io and build-push-action@2

* We try again

* Trying yet again

* Fix: Use actor and GITHUB_TOKEN

* Fix: Use github.actor in image tag path

* Fix: use github.repository_owner instead of github.actor
