DRA instructions missing safe-to-evict annotation on nvidia-driver-installer, preventing down scaling

node pools for the DRA instructions don't scale down because the nvidia-driver-installer manual install doesn't have `safe-to-evict` annotation.

Adding it like so fixed the problem:

```
kubectl patch daemonset nvidia-driver-installer -n kube-system -p         
  '{"spec":{"template":{"metadata":{"annotations":{"cluster-autoscaler.       
  kubernetes.io/safe-to-evict": "true"}}}}}'
```
