add user-assigned identity to worker nodes for CI version templates

[nojnhuh]

What type of PR is this?

What this PR does / why we need it:

In the wake of #4765 I noticed the Azure File/Azure Disk CSI driver tests were failing and it looks like because cloud-provider auth isn't working: https://testgrid.k8s.io/provider-azure-master-signal. This PR adds the user-assigned identity to worker nodes for the templates used by those tests so the CSI drivers which invoke cloud-provider from worker nodes can work as expected.
