Nightly cleanup workflow queries wrong registry #450
Description
Problem
cleanup-nightly-builds.yaml finds 0 nightly versions despite builds running daily.
Total versions found: 80
Nightly versions found: 0
Nightly builds push to quay.io/karpenter-provider-ibm-cloud/controller but the cleanup workflow queries GitHub Packages API (ghcr.io).
Fix
Update cleanup workflow to use Quay.io API instead of GitHub Packages API.
