Switch to unsup (packwiz compatible)

[coreknee]

I request that the auto updater used in the modpack be switched to https://git.sleeping.town/unascribed/unsup/ , due to more userfriendliness

i think we already went over this once and there were issues with it, they could be fixed by now, but it's way too late for that, i'm probably just going to leave it packwiz only

like if i use any unsup-specific features, that'd break the pack for everyone that already has a copy of it
