Someone should automate updating ansible roles as new ones come out for GAT

like, dependabot, but, somehow figuring out the diffs.

Start by examining how Ansible roles are currently used and updated in the GAT training material. Compare the requested behavior with Dependabot: the automation should detect new role releases and help identify the relevant diffs. There are no files, tests, or entry points named in the issue, so the implementation scope needs investigation first.
