docs: A checklist for all the things to check on a new minecraft version

[edayot]

A little bit of documentation on what to do when a new minecraft version comes out.
I didn't want the test I'd written to be blocking, as it might not pass very often, for example on old PRs. But I'm open to your opinions on the matter, as well as on the location in the guide documentation.

datapack.wiki has a breaking changes list. Might be looking into. I am working on a different repo that accomplishes something similar to this repo, and I found that if you want to fix breaking changes, just give ChatGPT the changes from datapack.wiki and give it the code base, summarized by repomix.com and ask it to "Find instances in this repository where the code it generates will break because of these breaking changes. Only include instances where the code it generates will break independent of the users input." It will soon give you a list of instances you can check and fix. If you don't understand, I can just do it when a new version comes out :)

I will redo this at some point
