Subject: [PATCH 1/3] Automate releases using GHA

To publish a release, we currently have to run `make docker-run-release` locally after tagging a release, which is not a huge effort but a bit cumbersome, because we do it only a few times a year and that is long enough to lose my memory :)

Starting this change, we use a GHA workflow to automatically build and publish binaries whenever a new semver tag is created, so that we do not need to run `make` anymore.
