Rename everything to .lua and give DataStore2 its own folder

[Kampfkarren]

Rotriever does not seem to support monorepos like this, so DataStore2 will have to be given special treatment. Also, .module.lua is an ancient file naming that has been superceded by simply .lua for a while.

Where are the docs for Rotriever?

Nowhere, it's not even available to the public yet. You can figure out generally what you're meant to do to use it though from repositories from Roblox engineers like https://github.com/osyrisrblx/t

At the very least, renaming the repo something else seems like a wise choice.
The name "Roblox" as a repo isn't really illuminating as to what this is, and indeed, I have gotten confused myself several times by it.
