Uses the workflow from the documentation which distributes the build for each platform on a separate runner. The result of such a run can be seen here, creating the images here.
Additional note: while macos-latest runs on M1, see here, docker is not yet supported, see here. So we currenly use ubuntu-latest to build both types of images: amd64 and arm64 via emulation.
