DevTest API returns resource group name in lower-case

👋

We've been working with version `2016-05-15` of the DevTest API's (via v20.1.0 of the Azure SDK for Go) - and have noticed a bug where the Resource Group name that's returned from Azure is always lower-cased for the ID, regardless of the input case. For example if I create a DevTest Lab in the resource group `Group1` the ID for create will be:

```
/subscriptions/00000000-0000-0000-0000-000000000000/resourceGroups/group1/providers/Microsoft.DevTestLab/labs/lab1/virtualnetworks/network1
```

when actually this should be:

```
/subscriptions/00000000-0000-0000-0000-000000000000/resourceGroups/Group1/providers/Microsoft.DevTestLab/labs/lab1/virtualnetworks/network1
```

Would it be possible to update this API to return the Resource Group name in the correct case, rather than lower-casing it?

Thanks!

Start by locating the DevTest API version 2016-05-15 specification for the virtual network resource and review how the resource-group segment is represented. Compare the documented identifier with the casing shown in the issue, then check the issue discussion for the agreed resolution. Done means the specification or responsible API behavior matches the original resource-group casing.
