fix: use clearanceCheckMask when checking for hand overlap

[meznaric]

HandPhysics stops working after you release an item.
Note: I had my own colliders around the hand which were overlapping with HandPhysics, and therefore after first pickup, you cannot interact physically with an item anymore. There is clearanceCheckMask that I believe serves the purpose of telling which items this check should ignore.

The clearanceCheckMask is defined and can be configured, but is simply not being used when hand releases an object.

This PR uses it in what I believe was intended place.

I can confirm it's working as it solved my bug.

How strange we missed that! Thanks for the pull. I'll integrate into the coming release.
