I wanted to try paragliders on my 1.20.2/fabric save, so I gave it a try and ported 1.20.1 to 1.20.2.

It seems OK at first glance but I have tested few features so far.
Here is a pull request. Feel free to review and test.
#110

I first upgraded all needed versions and added some lombok for convenience.
Then I tried to build and fix any compilation issue.
The main modifications relate to the Codec api introduced in the RecipeSerializer interface. Found some useful help there.
I tried to change the original code as little as I could so that the pull request may remain readable.
