Docs: add info about maintaining worlds

[black-sliver]

Adds responsibilities of world maintainers/authors to the docs and proposes some rules how to fairly vote in and out maintainers.

Who should we ping?

Just a couple of word choice changes that I think would make more sense for the reader to read.

Not sure staging is a proper term for unmaintained broken worlds i think deprecated is better, but otherwise i think this ok

Something like this would’ve been nice for when I took over RoR2, since I ended up needing to recreate the client for people to use. It took awhile for most people to realize that happened. I feel like for the voting part it should probably happen in discord, so that it is more public for everyone to know what’s going on.

I think staging is the proper name for it. Normally staging happens before it enters production, but in this case we move it "back into" staging. People can look at and use the worlds manually, but they are not part of the production build.

i feel deprecated might be a better name,
Actually might be even better to move them to different repo all together, so we don't have to keep maintaining them and fixing things in them to keep them compatible and not have their python test fail

I understand we want them to be easily visible for someone to pickup and breath new life into them. but it also should not slow down development on ap or other worlds as some old legacy that keeps hunting you or failing your pytests

[black-sliver]

if they are in a folder that is ignored, they don't impact development. doing git mv is free, moving to a separate repo is not. also the worlds are not deprecated, they are broken or incomplete.

i'm kinda with Jarno that i dont think "staging" is the right word to use for the folder to move unmaintained worlds too, but I also can't think of a better word either, as i dont think "depreciated" is much better. Other than this little gripe, LGTM

With the agreement to name it disabled ill approve this PR
