Add motion capture documentation for UE5 and etc

[SuraiaSilverbell]

Hello,

I am using SlimeTora for my HaritoraX wireless trackers and I'd love to be able to use them within Unreal Engine 5 where I am learning VR and Vtuber stuff.

But there currently doesn't seem to be any SlimeVR support for UE at all. Please add it!

Thanks.

You can use VMC. If you need help with setting it up, join our Discord and ask in the motion-capture channel ^^
