Update the Chameleon Outfit

[Flaborized]

I briefly checked the code for this to see if *other* chameleon outfits had gone outdated (some had) and while I was there I decided to just go ahead and make a fix PR. Rancher seems to already be in the list and fully functional so I just added the courier and fixed some things. Basically nobody (including me) ever remembers to update this thing.

No gimmick outfits added, I don't wanna make the list super long atm, someone else can PR that after if they think it's apt though.

edit: link to PR cuz I forgor https://github.com/goonstation/goonstation/pull/19576
