`AttributeError: 'list' object has no attribute 'get'` trying to use collection on recent Fedora (podman 5.0?)

Is this a BUG REPORT or FEATURE REQUEST? (leave only one on its own line)

Description

Trying to run an ansible-podman-based playbook which I've run many times without issue today, I ran into this:

TASK [podman : Create the pod] ***************************************************************************************************************************************************************
An exception occurred during task execution. To see the full traceback, use -vvv. The error was: AttributeError: 'list' object has no attribute 'get'

You can make that a bit more intelligible by replacing the "\n"s with literal newlines, it boils down to:

  File \"/tmp/ansible_containers.podman.podman_pod_payload_mgywsscc/ansible_containers.podman.podman_pod_payload.zip/ansible_collections/containers/podman/plugins/module_utils/podman/podman_pod_lib.py\", line 368, in diffparam_cgroup_parent
AttributeError: 'list' object has no attribute 'get'

the step that fails is just this:

- name: Create the pod
  containers.podman.podman_pod:
    name: bodhi-dev
    state: started
    publish:
      - "6543:6543"
      - "6544:6544"
      - "6545:6545"
      - "6546:6546"
      - "15672:15672"

Steps to reproduce the issue:

Install a recent Fedora 40 or 41, probably with podman-5.0.0~rc1-1.fc40 or newer (or, I guess, deploy podman 5.0.0 rc1 however you like)
Try and run a play with a straightforward containers.podman.podman_pod in it, as above

Describe the results you received: Boom! Traceback!

Describe the results you expected: A pod.

Version of the containers.podman collection: Either git commit if installed from git: git show --summary Or version from ansible-galaxy if installed from galaxy: ansible-galaxy collection list | grep containers.podman

Neither of the above, it's included in Fedora's ansible package, ansible-9.2.0-1.fc40.noarch. Code seems the same as current git head.
