fix(pmc): Removed hardcoded project name in update update_papermc.sh (#4225)

* fix: Removed hardcoded project name in update update_papermc.sh

Script was unable to fetch the proper builds for WaterfallMC due to it checking PaperMC instead.
Replaced the hardcoded .../paper/... project name with the already existing ${paperproject} to fix the issue
