Fixes "Pick up" in the shift-right-click menu not working in rare cases (#94992)

## About The Pull Request

Fixes it so if you're playing a basic mob with the dextrous component
(eg. gorilla, dextrous holoparasite), you can still use "Pick up" in the
shift-right-click menu.
This is a rare situation, and I don't know how many people even use the
old right click menu anymore, but it was annoying me while testing
something else so I fixed it.
This doesn't impact telekinesis, because you don't get that option on
the right click menu from a distance anyway.

## Why It's Good For The Game

I think the "pick up" option in the menu on an item should probably pick
up the item.
