To address DCO use git commit -s to sign off your commits, you can fix your current commit running: git commit -s --amend && git push -f

I'll ignore the Konflux failure as this is not applicable with a deployment change and I'm working on fixing that currently to unblock all promotion changes as they come.

The loop and logic for setting the stackDirs and stacksPath looks identical in check_non_terminating.sh and check_odov3, and is pretty similar in validate_devfile_schemas though I see it has more cases. Is there any way we can consolidate some of this so we don't need to change things in multiple places in the future?
