ci: use podman for simple GitHub workflows

`podman` is installed by default on the Ubuntu runners. Podman is
recommended for developers and contributors, as there are no elevated
privileges required to run it. Docker requires extra permissions to
build and or run container images, and contributors to Ceph-CSI should
not need to spend time working with that (several developers run the
`docker` command with `sudo`, which is discouraged).

Only the multi-arch Workflows require Docker, for the time being.
