Add Microsoft.Network/publicIPAddresses/delete permission

Fixes OCPBUGS-60385: Missing Azure permissions for public IP cleanup

This permission is required for the DeletePublicIP function in the
Cloud Controller Manager to properly clean up orphaned public IP
addresses when LoadBalancer services are deleted.

Code location:
- File: pkg/provider/azure_publicip_repo.go:81
- Function: DeletePublicIP
- API call: NetworkClientFactory.GetPublicIPAddressClient().Delete()
