Fix for hands trackers not lining up properly in SteamVR

[Sebane1]

A somewhat simple fix for an issue I found during my investigations of using SlimeVR trackers as hand controllers.
I noticed a skeleton offset on the hands was causing them to not align properly in SteamVR, and they now line up correctly with this adjustment.

Wouldn't the proper solution be to just set the config to 0? I'm pretty sure the Z offset is for using controllers as hand trackers, which is the majority use-case.

I don't think SlimeVR is typically handling the hands at all which is why the offset hasn't previously been problematic. Maybe the config "could" be zero'd out, but I didn't see the benefit of any config storage for this value. I haven't noticed any negative impact between continuing to use proper controllers, or using slimes in place of controllers with this change.

Semantically, the config could exist, but I'm not sure of the benefit.
