MayaReference not loading in Maya 2022

**Describe the bug**
Loading in a MayaReference i.e a rig into the proxyshape doesn't work.

**Steps to reproduce**
Steps to reproduce the behavior:

Load the asset layer from [asset.zip](https://github.com/Autodesk/maya-usd/files/13346044/asset.zip) - make sure model.usda and the two rigs are in the same directory
Expand the proxy in the outliner to the /cube prim -
Set the rig variant to layout or render
Observe no rig is loaded in Maya 2022

**Expected behavior**
The rig to load to load in Maya 2022.

If it can't be fixed, please deactivate this feature in Maya 2022 if this is not a supported feature.

Digging around a bit it seems that this only works in UFE 3.0 which the devkit for maya 2022.3 doesn't have. . It works in Maya 2023 and onwards.
