Add outputs for Kubernetes cluster token and CA certificate, fix auto_scale (#20)

* Add outputs for Kubernetes cluster token and CA certificate. to be used by k8s and helm tf provider inputs

* Update node_count logic to support auto-scaling in Kubernetes cluster configuration

* Fix node_count lookup to use each.value for Kubernetes node pools

* Fix node_count lookup to reference node_pool.value for accurate Kubernetes configuration

* Update Kubernetes cluster version to 1.31.1-do.5. 1.27 is no longer an option or supported
