GKE cluster versions have been updated. New versions available for upgrades and new clusters

## Change #### (2024-R30) Version updates GKE cluster versions have been updated. **New versions available for upgrades and new clusters.** The following Kubernetes versions are now available for new clusters and for opt-in control plane upgrades and node upgrades for existing clusters.

This issue specifically affects clusters with [GKE Subsetting](https://cloud.google.com/kubernetes-engine/docs/how-to/internal-load-balancing#subsetting) and Services with `externalTrafficPolicy=Cluster`. This issue is more likely to occur in clusters with more than 25 nodes. To prevent this issue altogether, we recommend updating your Service configuration to use `externalTrafficPolicy=Local`. If you're already experiencing downtime, scale up the number of pods backing your LoadBalancer to provide immediate relief. A fix for this issue will be available in upcoming GKE releases.
