Give Lead Attachment to Wandering Traders

Wandering traders are the only mob in the game that can naturally spawn holding leads, so I think it would be a good addition for players holding leads to be able to give their leads to wandering traders to hold (ie. if you are holding a lead attached to a chicken, you could right click on a wandering trader with that lead and that wandering trader would now be holding the chicken).

Given the new 1.21 update and leads now being able to be attached to boats, I think that this could create some interesting transportation and automation possibilities.  I think this would be a cool mechanic, and I don't really see any downsides resulting from it.
