[Documentation request] Mention this repository on the Unity docs for the Unity launcher's VR template project

[Hunter Bobeck]

Hi –

The following docs:
https://docs.unity3d.com/Manual/xr-template-vr.html

...don't mention this repository. It initially appears as though controller tracking and inputs don't work in the VR template project. Such basic aspects of creating a VR project, as offered by this repository, ought to at least be mentioned by the documentation for a VR template project. It requires some searching to realize that Unity offers this repository as well.

Hoping to help save other developers time by suggesting this documentation improvement.
Thanks for considering.
