[BUG] When the gltFast project hits its Git LFS limit, the MRTK3 sample project fails to work

[ms-RistoRK]

Describe the bug

A fresh clone of MRTK3 main branch repo fails to load in Unity Editor with Unity Package Manager Error shown next:

To reproduce

1. Clone MRTK3 main branch locally
2. Use Unity Hub to add project located in \UnityProjects\MRTKDevTemplate
3. See error

Expected behavior

After Step 2, Unity Editor should open, import packages, without displaying any Unity Package Manager Error.

Screenshots

Your setup (please complete the following information)

• Unity Version 2021.3.21f1
• MRTK Version: 3 or Commit [e.g. v3.0] [e.g. 3aa92c5]

Target platform (please complete the following information)

• Windows 11 Desktop

Additional context

It seems that a package from https://github.com/atteneder/glTFast is registered in the package manager.

This in some way is an external issue. We can look at updating the sample to Unity gltf plugin instead, which wouldn't have the same issues.

[ms-RistoRK]

Won't fix because:

• We lack the resources to exhaustively test the proposed fix in all devices where MRTK3 is deployed and Qualcomm has suggested to test the proposed fix on their devices.
• The issue is known and accepted. For historical reference: The PR that was proposing a solution is this one: https://github.com/MixedRealityToolkit/MixedRealityToolkit-Unity/pull/631
