[BUG] PUT Microsoft.Databricks/workspaces/{name} does not return back properties.parameters.vnetAddressPrefix

### API Spec link

https://github.com/Azure/azure-rest-api-specs/blob/main/specification/databricks/resource-manager/Microsoft.Databricks/stable/2024-05-01/databricks.json

### API Spec version

2024-05-01

### Describe the bug

The properties.parameters.vnetAddressPrefix set in workspace creation is not returned back in the GET response. This is problematic for Terraform because it mistakenly thought the state has been modified (the value is deleted).

Refer to https://github.com/hashicorp/terraform-provider-azurerm/issues/30209

### Expected behavior

The properties.parameters.vnetAddressPrefix set in workspace creation should be returned by the GET API.

### Actual behavior

The properties.parameters.vnetAddressPrefix set in workspace creation is not returned by the GET API.

### Reproduction Steps

```bash
az rest -m PUT \
-u '/subscriptions/{subId}/resourceGroups/{rgName}/providers/Microsoft.Databricks/workspaces/{name}?api-version=2024-05-01' \
-b @./path/to/payload.json
```

payload.json
```json
{
"location": "australiaeast",
"properties": {
"managedResourceGroupId": "/subscriptions/*****/resourceGroups/*****",
"parameters": {
"enableNoPublicIp": {
"value": false
},
"prepareEncryption": {
"value": false
},
"requireInfrastructureEncryption": {
"value": false
},
"vnetAddressPrefix": {
"value": "10.141"
}
},
"publicNetworkAccess": "Enabled"
},
"sku": {
"name": "premium"
},
"tags": {}
}
```

### Environment

_No response_

Start in specification/databricks/resource-manager/Microsoft.Databricks/stable/2024-05-01/databricks.json, focusing on the workspace parameters schema and vnetAddressPrefix. Use the provided az rest PUT payload and then inspect the GET response; done means the value set during creation is represented in the GET API response.
