Add an a-pack release file (package format for Alpine)

[John15321]

Crate a package generating release CI job in the release workflow for our project which should later be added to the release files. Bare in mind that a new testing CI job will be required to make sure it's working. The package should be for Alpine (preferably find a tool similar to (cargo-deb that generates it from a rust project).
