### API Spec version

2023-10-01

### Describe the bug

The specification for Azure ML `ComputeInstance` doesn't contain the `idleTimeBeforeShutdown` property while it's returned by the actual API. As a result https://github.com/hashicorp/go-azure-sdk doesn't contain this property and https://github.com/hashicorp/terraform-provider-azurerm can't be changed to manage it via Terraform.

### Expected behavior

The specs for the `ComputeInstance` contains the `idleTimeBeforeShutdown` property

### Actual behavior

The `idleTimeBeforeShutdown` property is missing in the specs for the `ComputeInstance`

### Reproduction Steps

Run
```
az rest --method get --url https://management.azure.com/subscriptions/xxxx/resourceGroups/xxxx-rg/providers/Microsoft.MachineLearningServices/workspaces/xxxx-mlw/computes/xxxx-test-instance?api-version=2023-10-01
```

and find the `idleTimeBeforeShutdown` in the output
