Non terminating image check does not support parent in devfiles

Bug Summary

The check_non_terminating script is failing in case a registry stack is using a parent devfile.

Describe the bug:

As the devfile is not flattened before checking for non terminating images, the script is unable to find any components.

To Reproduce:

Create a registry stack that has only a metadata & parent section. An example is here: https://github.com/devfile/registry/actions/runs/9259636857/job/25472255936?pr=401

Expected behavior

The check should be passing and the devfile should be flattened during the execution of the script with all the parent components.

Any logs, error output, screenshots etc? Provide the devfile that sees this bug, if applicable

Logs can be found here: https://github.com/devfile/registry/actions/runs/9259636857/job/25472255936?pr=401

Testing /home/runner/work/registry/registry/stacks/ollama/devfile.yaml
  COMMAND: minikube ssh docker pull null

One solution would be to invoking the devfile/library cmd and flattening the devfile before examining it. The devfile/library module might not have the flattening available via their main(), so we will need to update that main() a bit.

+1 I think exposing this functionality might also be useful for future cases where we need to obtain the flattened version of a devfile easily
