Try to not use podman - some tar and pipe problems

Problem happens after all tests pass:

Run command with stdout: podman exec --user pytest -i ansible-test-controller-hLEbtZTx sh -c 'tar cf - -C /root/ansible_collections/scale_computing/hypercore/tests --exclude .tmp output | gzip'
Run command with stdin: tar oxzf - -C /home/runner/work/HyperCoreAnsibleCollection/HyperCoreAnsibleCollection/ansible_collections/scale_computing/hypercore/tests
WARNING: Command "tar oxzf - -C /home/runner/work/HyperCoreAnsibleCollection/HyperCoreAnsibleCollection/ansible_collections/scale_computing/hypercore/tests" returned exit status 2.
>>> Standard Error
gzip: stdin: unexpected end of file
tar: Unexpected EOF in archive

Maybe this will help.
