Instead of using gox on one side and an action to release, we can merge them together with goreleaser which will build for extra targets (arm, mips if needed in the future) and it also takes care of creating checksums, a source archive, and a changelog and creating a release with all the artifacts. All binaries should respect the old naming convention, so any scripts out there should still work. Signed-off-by: Itxaka <igarcia@suse.com>
