### Confirm

- [X] I have read the troubleshooting guide and looked for duplicates.

Start with the Microsoft.MachineLearningServices/workspaces definition for API version 2023-02-01-preview and inspect the WorkspaceProperties type. Update the resource definition so the managedNetwork property in the Bicep repro is accepted, then validate that the reported type error no longer occurs.
