Bug Report

Describe the bug

When changing the Kubernetes version from 1.21.9-do.0 to 1.22.13-do.0, Terraform generates the following plan:

  # module.kubernetes_cluster[0].digitalocean_kubernetes_cluster.app will be updated in-place
  ~ resource "digitalocean_kubernetes_cluster" "app" {
        id             = "ce51ac35-9dd4-4a35-88c5-45581ada98f5"
        name           = "app-prod"
        tags           = []
      ~ version        = "1.21.9-do.0" -> "1.22.13-do.0"
        # (14 unchanged attributes hidden)

        # (3 unchanged blocks hidden)
    }

After successful apply, checking the Kubernetes version using doctl shows that the version is still 1.21.9-do.0, and running terraform plan again generates the same plan as before.

Affected Resource(s)

digitalocean_kubernetes_cluster

Expected Behavior

Kubernetes cluster should be on version 1.22.13-do.0.

Actual Behavior

Kubernetes cluster stayed on version 1.21.9-do.0.

Steps to Reproduce

terraform plan after changing the version of the Kubernetes cluster in Terraform.
terraform apply
Check cluster using DO, try creating a plan again.
