[CI:BUILD] followup PR for fcos with podman-next

Followup on #19477

Remove commented out cirrus task for fcos image build with podman-next
and add 2 github actions: 1 for running a simple uni-arch image build
on every PR and another to actually build multiarch images and push to
quay after merge.

`podman --version` will also include git short sha for clarity.

[NO NEW TESTS NEEDED]
