ibutsu-pod.sh script doesn't account for Container image short names in Podman

[EliadCohen]

See: https://www.redhat.com/sysadmin/container-image-short-names

If the script is run while short-name-mode="enforcing" (registries.conf) the script will fail when prompting user to pick an unqualified registry to search in (because there's no tty)

Consider checking registry.conf for this key and suggest to the user to set it to:
short-name-mode="permissive"
