Adding Coats to the Staff Officer vendor (#3840)

# About the pull request

Title.

![image](https://github.com/cmss13-devs/cmss13/assets/102828457/3f83c54f-3cf0-4227-a1f0-8a1b9b10baf4)
I am willing to toss the Tanker Jacket, as much as I miss it.
I also added the uniform to their required gear for the sake of
consistency.
# Explain why it's good for the game

It gives the SO more options for clothing, as it's cold on the ship.
I've also removed the free helmet they could get, for some odd reason.
