Add a line to the F3 screen saying which version the current chunk was generated in

Title says it all: given the huge changes to the world generation underground, I think it would be extremely valuable to be able to tell at a glance if you're in a pre-1.17, 1.17 or 1.18 chunk if you're looking for new features.

I'm currently working on a new branch mine a distance away through a nether shortcut, but occasionally I pass through areas I've already generated while exploring aboveground, and it's not immediately apparent until I do a doubletake and realize I haven't seen any deepslate or copper.

Being able to know which chunks are newly generated would have applications for those who retain a world between versions. For instance: once 1.18 rolls around, knowing immediately if there's a -Y layer in your chunk would also be great QoL for legacy worlds. It would also help those who want to know if the current chunk has been affected by any recent fixes, such as the 1.17.1 diamond generation fix.

Obviously this wouldn't be able to support older chunks, but given the upcoming changes in 1.17.1 and especially 1.18, it's probably best to do it sooner rather than later. It would be as simple as a version code in the chunk file, and a single line in the debug screen.

I can't post this on the feedback site, as the login redirect is currently broken on my end, so here will have to do.
