Pin kubectl and kind node image to a single KUBE_VERSION variable in kind.sh instead of fetching the latest version dynamically from dl.k8s.io/release/stable.txt at build time, which sometimes break CI. Restore the --config flag on `kind create cluster` that was lost in commit 1535ce6 when the workflow was refactored from inline steps to kind.sh, and pass --image from the centralized version. Remove the duplicated image: field from kind.yaml since it is now controlled by the CLI flag.

Use containerdConfigPatches instead of replacing the entire containerd config. The custom config was missing critical settings like SystemdCgroup, preventing pods from starting. Wait for the API server healthz after kubelet restart in the CRI auth path.

Also try to address some of the other flakiness of the e2e k8s jobs I've seen.
