Makes the wizard's pets not fight to the death (tgstation#81412)

## About The Pull Request

Adds the `"Wizard"` to the wizard's pets Jimmy and Jommy, preventing
Jimmy from killing Jommy and trying to kill his owner.

Fixes tgstation#81410

## Why It's Good For The Game

The wizard federation is supposed to train their pets better than this.
