Adds The Sturdy Shako (HoS Hat) (#74277)

## About The Pull Request

Adds a new craftable HoS shako, made from the standard peaked cap and
some plasteel and gold.


![shako](https://user-images.githubusercontent.com/5479091/227799392-ad2ea145-5c58-45d7-8763-a76e9323ec09.png)

Moves the HoS cap into a subtype `/obj/item/clothing/head/hats/hos/cap`
to avoid catching the beret in the crafting recipe, the base type
`/obj/item/clothing/head/hats/hos` is now a generic subtype which should
never exist.

(Yes there's a TF2 reference included with the hat)

## Why It's Good For The Game

Adds an additional level of style for an HoS willing to put a little
effort into gathering the required materials. As it is crafted as a
one-to-one trade with another headgear there is no additional spare
headgear introduced.

## Changelog
🆑
add: The Nanotrasen Costuming Department has released specifications for
how to convert the Head of Security's cap into a shako.
