Pet collar bugfixes (#94309)

## About The Pull Request

~Since you can't wear pet collars and the bartender doesn't have a pet,
I'm not sure why they're in the bartender drobe and bartender clothes
locker. I removed them.~

Also, the felinid deathmatch loadout is supposed to spawn with a pet
collar equipped but can't since they aren't wearable by humans so now
they spawn with an alternate version that is wearable and NOT OBTAINABLE
OUTSIDE OF DEATHMATCH.

## Why It's Good For The Game

bugfix

## Changelog

fix: Deathmatch felinids now spawn in with pet collars as intended
