- Fixed plugin not packaging due to missing Metahuman reference
- Fixed plugin not packaging when OpenXR plugin disabled

- Updated documentation on getting started with Android/XR2 platforms
Known issues:
- Text colour in UI interaction drop downs wrong (UE5 bug)
- Running VR with OpenXR via SteamVR doesn't see VR (UE5 bug). To work around, enable the SteamVR plugin in the project.
- In UE5, grabbing with the right hand motion controller is intermittent
- HMD offset is not set automatically for SteamVR devices and should be set manually for your headset in the IEPawnHands blueprint.
- As with most Unreal 4 VR projects, when run in VR preview in the editor, full framerate is often not achievable. This is fine when packaged.
- Auto calculating orientations with imported meshes that have negative scales require manual correction to the PreBaseRotation.
- Using the SteamVR plugin only, motion controller models are not visible when auto switching is enabled.
