name: ARC upgrade

# Runs the ARC role's CRD handling against a kind cluster (tests/arc_upgrade/run.sh): installs the controller chart at an old version, shows the newer scale-set chart is rejected against those CRDs, applies the CRDs the way the role does, and shows it is then accepted.
#
# GitHub-hosted ubuntu-latest has Docker, kind, kubectl and helm already.
