// upgradeVersionFieldPaths lists the nested config paths that carry a per-minor
// "version info" value. They mirror the version pins defined in
// roles/defaults/vars/v1.{m}.yaml (helm/sandbox/etcd/cri/cni/dns/storage/registry
// versions). This is the ALLOW-LIST used to construct an explicit intermediate-hop
// version overlay from that embedded vars file: for each intermediate hop we read
// the value of every listed path from roles/defaults/vars/v1.{hop}.yaml and SET it
