Allow playing on 1.21.0

It shouldn't hurt to do this.

If you're a player, I'm sorry that you're stuck on this version.

If you're a modder who has done what the branch's title is, update your damn mod version!
~1.21 is good enough even, it's better to error on future MC versions instead of what's a patch version.

Porting Lib devs, feel free to reject. I understand if y'all don't want this. I wouldn't want to support what's basically a version of the game that has a really bad exploit either.

I don't really have a problem with this being merged, but what needs to be made sure is that fabric API for 1.21.1 has the same type of dependency

Mhm, we might need to test it a bit to make sure that everything works on the latest 1.21.0 FAPI.

It does. I don't think they did anything outside of new api changes.

1.21.0 is one of the versions that it’s not possible to be stuck on. Doing this only adds another version to support for no reason
