az sentinel data-connector create returns an error

**Describe the bug**
Using ```az sentinel data-connector create``` with the expected arguments produces an error and the data connector is not created.

Error returned:
```
(BadRequest) Failed to parse input. Error='Required property 'dataTypes' not found in JSON. Path 'properties', line 3, position 17.'
Code: BadRequest
Message: Failed to parse input. Error='Required property 'dataTypes' not found in JSON. Path 'properties', line 3, position 17.'
```

**To Reproduce**
Enter the following command in a desktop PowerShell window or the Cloud Shell on the Azure portal:
```az sentinel data-connector create --office-data-connector tenant-id="{11111111-1111-1111-1111-aaaaaaaaaaaa}" --data-connector-id "{11111111-1111-1111-1111-bbbbbbbbbbbb}" --resource-group "myResourceGroup-DKS" --workspace-name "myWorkspace-DKS"```

**Expected behavior**
No error and a created data connector.
