Website: Add possibility to add information about VR hardware the game was tested with

[tgurr]

VR games e.g. https://www.protondb.com/app/916840 currently seem to lack a way to show the hardware information (right side among CPU/RAM/GPU) about the vr headset that was used to test which would be incredible useful now that more and more are popping up and show different behaviour and have different hardware features to take into consideration.
