Deletes the warden's evidence bag (#94639)

## About The Pull Request

Warden's bag spawns with nothin' but their box. 

## Why It's Good For The Game

I understand the thought process behind giving sec-offs evidence bags
...but the warden doesn't leave the brig - you know, the place where you
readily have a supply of bags?
Idk why *they* need to spawn with one. 

## Changelog

del: Wardens no longer spawn with an evidence bag
