Describe the bug sometimes a disk isn't erased with terraform destroy -auto-approve when one or more are associate with a vm

To Reproduce Steps to reproduce the behavior:

1. build up some terraform with a vm and disks
2. apply
3. destroy with the -auto-approve

Expected behavior disks to be cleaned up and terraform to not error out

Environment

• Harvester ISO version: v1.3.0 / v1.2.1
• Underlying Infrastructure: baremetal

Workaround

• manually remove the volume

I encountered this before (https://github.com/harvester/harvester/issues/5573), there is an option called auto_delete, add this to the disk config and the volumes should be erased after execute terraform destroy -auto-approve

disk {
  name = "test-disk"
  size = "10Gi"
  image = "ubuntu"
  auto_delete = true
}
