Compact shotgun re-added (#77759)

## About The Pull Request

This pr seeks to re-add the compact shotgun (slightly buffed with 1 more
ammo) and buff up its larger brother the combat shotgun (with 2 more
ammo.)

## Why It's Good For The Game
With the recent laser buffs, there is a real possibility for the compact
shotgun to return as a unique weapon to make the HOS slightly more
powerful. I am aware that it was a warden's weapon previously but the
HoS doesn't really have many fun toys to play with. The warden already
has crav maga (100x cooler than the laser) so giving this beast to the
HOS could help make it a more attractive and powerful head to play.
(Given 1 extra shot to keep up with the crazy lasers nowadays.)

In regards to the slight combat shotgun buff. The gun itself is ass,
it's barely ever used and the riot shotgun is superior because you can
actually put it in your armour slot. The hope is that this buff will
make people actually use it because it carries a lot of shots now so the
viability may increase.
