kubeadm: get k8s CI version markers from k8s infra bucket

Browse Source 
Updates kubeadm version resolution to use kubernetes community infra
bucket to fetch appropriate k8s ci versions. The images are already
being pulled from the kubernetes community infra bucket meaning that a
mismatch can occur when the ci version is fetched from the google infra
bucket and the image is not yet present on k8s infra.

Follow-up to kubernetes/kubernetes#97087
