[PATCH v6 3/6] containers/builder: Dockerfile creation script

[Ali Alnubani]

> This script is not intended to be run by the end user on their machine's bare environment. The CI worker container will acquire the needed python version to run this script when the container is built; the end user does not need to install python 3.10 themselves. The "make_docker_files_in_container" target in the Makefile is the intended way to call this script. The build and push targets then depend on that target.

That's fine to me as well.

Thanks,
