MayaReference not loading in Maya 2022

[DanEnglesson]

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 - 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.
