feat: add alpine ci

notes:
- to build the package, you must use the cargo version from the edge branch
  (by building on edge or by installing it manually)
- building from git requires some work (abuild supports snapshots for getting
  the release from git, but the version number would remain unchanged)
- the apkbuild doesn't include any packaging tests (as i don't know what to include)
