Unable to Make Changes to Rancher Cluster Due to Invalidly-Specified Nodepool Incompatibility

[justdan96]

We recently went through a process of upgrading a cluster control plane, and introducing new nodepools to match that control plane version. The issue is that the eks-operator component is blocking any Terraform changes to that cluster because it thinks the nodepools are incompatible. This is despite us being within the version skew policy specified by the Kubernetes docs: https://kubernetes.io/releases/version-skew-policy/

The exact error message we see in Terraform is:

Error: Cluster ID c-XXXXX: versions for cluster [1.29] and nodegroup [1.27] not compatible: all nodegroup kubernetes versionsmust be equal to or one minor version lower than the cluster kubernetes version
