Release ARM Binaries

[Dav1dde]

Now that we have ARM docker images, Releases should also build ARM binaries.

We do have people directly consuming/using the released binaries from the job but not the docker images (for example @stayallive).

We should employ the same tech and build these binaries the same way we do build the docker images.

The docs also mention downloading the binary directly from the GitHub Releases as another option besides the Docker images. I'm using this URL in for example a Ansible playbook to deploy Relay to my fleets.
