This PR adds an Alpine package registry. You can follow [this tutorial](https://wiki.alpinelinux.org/wiki/Creating_an_Alpine_package) to build a *.apk package for testing. This functionality is similar to the Debian registry (#22854) and therefore shares some methods. I marked this PR as blocked because it should be merged after #22854.  --------- Co-authored-by: techknowlogick <techknowlogick@gitea.io> Co-authored-by: silverwind <me@silverwind.io> Co-authored-by: Giteabot <teabot@gitea.io>
