/kind bug

Description

Pushing an image with / in the name to a remote registry does not work.

Steps to reproduce the issue:

1. Set up a registry at localhost:5000

2. Build an image with a slash in the name, e.g. jlk/archlinux (or just foo/bar)

3. Try to push the image to the remote registry with the containers.podman.podman_image module

Describe the results you received: An error (see below).

Describe the results you expected: Successful push.

Additional information you deem important (e.g. issue happens only occasionally):

The code only appends the destination argument when / is not present in the name: https://github.com/containers/ansible-podman-collections/blob/c3b38b54a95a40588cda7124b1879bc161c7f08d/plugins/modules/podman_image.py#L755-L757

So in my case the module executes only podman push jlk/archlinux and the destination gets resolved to docker.io via unqualified-search-registries configuration. However, if the destination was not omitted, the command would be podman push jlk/archlinux jlk.fjfi.cvut.cz:5000/jlk/archlinux (and running this manually succeeds).
