Build for the local arch but push for amd64 and arm64. Use the custom
container-builder buildx platform. Also update the docker-compose file
on release.
Docker-run was only useful in very specific projects. Projects should
either define their own "run" in their Makefile, add a
docker-compose.yaml, or specify instructions in the README.
Instead of putting everything in one makefile switch to a folder called
"make" with multiple makefiles. Move the original makefile to
"docker.makefile" and add kaniko and truenas to fill in later.
