az network bastion create --vnet-name does not accept resource Id

### Describe the bug

I wanted to deploy Bastion into its dedicated resource group where there is no Virtual Network present. For this reasons I tried to pass the virtual network's resource Id as `--vnet-name` but it didn't work as the CLI tried to append the whole resource ID to the resource Id of the subnet.
