Minor spelling mistake in Slime Management Console (#94978)

## About The Pull Request

The Slime Management Console will include a random stored_monkeys in a
to_chat if there aren't enough. This removes it so that it reads better.

## Why It's Good For The Game

Reads like proper english in a player facing console.

## Changelog


🆑
spellcheck: The slime management console no longer reads a variable name
out incorrectly.
