Update the release process

- Drop the custom made tarball: We now rely on [signed git tags](https://gitlab.archlinux.org/archlinux/packaging/packages/archlinux-contrib/-/commit/50905be547cd72eb1bcd1efab5b988e00781b883) for the package, which is more straightforward and transparent. IMO there's no need to keep creating this extra tarball.

- Move the whole release process into a single `release` target

- Switch to `gh`: `hub` throws an error (not sure if it's broken or expects something missing)

- Document the release process in the README
