ci: add push-triggered stub delegating to fog-workflows version check (feature-ldap-rbac)

[darksidemilk]

Summary

Same stub as #922/#923, targeting this branch. Existing feature-*/rc-* branches don't automatically inherit the stub added to dev-branch (#923) since they predate it, so it needs to land here too for pushes on this branch to be watched — see #922 for the full rationale.

Test plan

• Merge, then confirm a push to this branch triggers the fog-workflows reusable workflow and correctly computes/fixes drift if any exists.

Superseded — this stub was part of yesterday's first attempt at the FOG_VERSION check, which turned out to have a self-triggering commit loop bug (see the rewritten docs in FOGProject/fog-docs#72 for the full story). That design has been replaced with a single hourly-schedule workflow in fog-workflows that discovers watched branches itself via the GitHub API, so there's no stub file to propagate into fogproject at all anymore. Merging this would just add a dangling uses: reference to a workflow that no longer exists in fog-workflows.
