Subject: [PATCH] dev: ci: build Docker images

Uses the existing in-tree Dockerfile to build Docker images when
a release is made and everytime there is a merge to master.
Publishes the images to the GitHub Container Registry as well.
Heavily based on https://docs.docker.com/build/ci/github-actions/examples/
