The Create Cluster warning explained the beta-API creation-time constraint but not which GKE versions work. Clarifies the two supported configurations: **GKE 1.36 with the beta APIs enabled at cluster creation**, or **GKE 1.37+** where `certificates.k8s.io/v1beta1` is served by default (no beta enablement needed). Versions below 1.36 are unsupported. - [x] Tests pass (docs only) - [x] Appropriate changes to documentation are included in the PR --- Also updates `hack/ate-dev-env.sh.example`: it pinned `1.35.5-gke.1163012` — below the supported floor and no longer offered, so copying it verbatim failed cluster creation. Now pins the newest offered 1.36 patch (`1.36.3-gke.1767000`) with a comment on how to pick a fresh one when the pin ages out. **Validated**: `setup-gcp create cluster` at `1.36.3-gke.1767000` (us-west1-c) succeeded, and both `certificates.k8s.io/v1beta1` APIs (`clustertrustbundles`, `podcertificaterequests`) are served on the resulting cluster — `kubectl get clustertrustbundles` returns the kube-apiserver-serving bundle. Throwaway cluster deleted after verification. --------- Co-authored-by: Aditya Shantanu <aditya-shantanu@users.noreply.github.com>
