[BUG] Undocumented challenges of setting up QEMU in public GHA #34

Version

redhat-actions/push-to-registry@v2.2

Describe the bug

$sbj. README says to use https://github.com/marketplace/actions/docker-setup-qemu but that does not work (I don't have a log anymore but it said something about the wrong architecture when I tried to build AARCH64 with archs: linux/arm64 set).

I managed to make it work by using

- name: >-
    Set up QEMU ${{ matrix.IMAGE.QEMU_ARCH }} arch emulation
    with Podman
  if: matrix.IMAGE.QEMU_ARCH == 'arm64'
  run: >-
    sudo podman run
    --rm --privileged
    multiarch/qemu-user-static
    --reset -p yes

I think it's worth documenting in README. And as a bonus, maybe it's worth wrapping this as an action mirroring docker/setup-qemu-action to encapsulate this command similar to other related actions.

Or maybe detect what the users set in the archs input and do this implicitly in this action.
