podman_image module uses 'podman push' command with wrong
flag '--remove_signatures' instead of '--remove-signatures'
This patch fixes the given typo.
Fixes: ansible/ansible#67965

with force: true, podman_image would always report changed regardless
of whether or not the pull or build operation resulted in a new image.
With this commit, check the image digest before and after and only
reported changed if the digest is different.
