Empty "virtualHubRouteTableV2s" in VHubs #32704
Description
Describe the bug
When listing or showing a virtual hub, the JSON response field "virtualHubRouteTableV2s" comes back empty, even though we have at least two custom vhub route tables associated with vhub connections on that vhub.
For context, here's the list of route tables on that vhub:

No errors, but the returned JSON should contain the list of route tables associated with the vhub, and it doesn't.
