[IotHub] The actual return value of the delete operation is not consistent with Swagger

Delete a privateEndpointConnections

In the definition of swagger, it should return "#/definitions/PrivateEndpointConnection" when the status code is 200 or 202, but it actually returns

{"status":"Running"}

{"status":"Succeeded"}

Delete an IotHub

In the definition of swagger, it should return "#/definitions/IotHubDescription" when the status code is 200 or 202, but it actually returns

{"status":"Running"}

{"status":"Succeeded"}

Start with the linked iothub.json definitions around lines 274 and 2007, then compare their documented responses with the Running and Succeeded payloads in the issue. Determine whether the specification or service behavior is intended, and confirm that both delete operations consistently document or return the same response shape.
