[BUG] `rancher2_etcd_backup` is not populating the Kubernetes version when creating a snapshot

[markusewalker]

Rancher Server Setup

• Rancher version: v2.8.0
• Installation option (Docker install/Helm Chart): Docker
  • If Helm Chart, Kubernetes Cluster and version (RKE1, RKE2, k3s, EKS, etc): RKE1
• Proxy/Cert Details:

Information about the Cluster

• Kubernetes version: v1.27.8-rancher2-1
• Cluster Type (Local/Downstream): Downstream
  • If downstream, what type of cluster? (Custom/Imported or specify provider for Hosted/Infrastructure Provider): Linode

    When using the rancher2_etcd_backup resource block with a provisioned RKE1 downstream cluster, the ETCD snapshot is created as expected. However, the issue is that the kubernetesVersion does not get populated as expected. This causes issues as when you attempt to restore the created snapshot, you are unable to do so as you receive an error.

    To Reproduce

    1. Setup Rancher.
    2. Provision an RKE1 downstream cluster as a standard user using the rancher2_cluster resource block.
    3. Once provisioned, use the rancher2_etcd_backup resource block; validate that the Kubernetes version is blank.
    4. See the below main.tf as a reference:

       
       terraform {
       required_providers {
       rancher2 = {
         source  = "rancher/rancher2"
         version = "3.2.0"
       }
       }
       }

    provider "rancher2" { api_url = var.rancher_api_url token_key = var.rancher_admin_bearer_token insecure = true }

    ### Actual Result
    <!-- A clear and concise description of what actually happened. -->
    Creating an etcd backup should successfully populate the Kubernetes version.
    
    ### Expected Result
    <!--A clear and concise description of what you expected to happen.-->
    Creating an etcd backup DOES NOT populate the Kubernetes version.
