A little suggestion, make a repository for the wiki where people can contribute changes and/or add their own pages.

Unfortunately, that's not supported by GitHub.

You can clone the wiki locally and make changes that way, and then open an issue I guess.

git clone https://github.com/lucko/LuckPerms.wiki.git

I meant like a repo that you would check every now and then, and then you would update the actual wiki with the changes/additions u like.
