Hi @cpanato, thank you for this PR.

Could you run through a basic test on your repo please? Both for a build, and a release. The release will push a Docker image if it's working right.

Given the way the GH actions work, it templates your username and uploads an image to your own custom GHCR.io repo for testing.

We can also move to secrets.GITHUB_TOKEN now instead of individual secrets that I create and manage.
