Update to 1.20.2

[ghost]

Sorry for having this deleted before, original PR message below:

Been told #84 is urgent to merge otherwise built artifacts would be broken otherwise.

At the moment I've only updated versions to track with the latest FLK and get it to compile with 1.20.2. There are some other changes which should likely be addressed before this gets merged:

• The annotation @CodecSerializable.Polymorphic is not top level, @MetaSerializable used to allow this however it's now been deprecated and it only supports top level annotations.
• There has been networking refactors and I or someone else probably need to add more extensions for those.
• Parts of the code base is generated with Silver's math codegen project, those haven't been looked at but may need some updating.
• Fabric Language Kotlin's language adapter seems to have broken due to changes in Kotlin 1.9.20, should verify our language adapter still works: Changes for upstream since last bump
• Switch to using Yumi Licenser

I'll try and recap the other messages I sent, but I didn't save them like the original:

1. It seems like math types haven't changed between 1.20.1 and 1.20.2
2. Some of the methods have been renamed to match QSL, therefore API breakage, also fixed a deprecation with the annotation mentioned not being top level which is another breaking change.
3. Fixed licenser not working on java files in addition to switching to yumi-licenser.
4. Found out object function entry points didn't work when testing the language adapter so fixed that as well.

Looks good, just want a quick confirmation that it can be merged as well as that the codec changes didn't accidentally break things, as that looks like it's probably the most fragile

I was unaware of any Codec changes tbh, I assume any tests would have ran and passed, Codecs otherwise aren't in my area of expertise, if there's any notable mod I can test with real quick I'll give that a shot.

Sadly it appears there are Codec issues in the samples I didn't spot before. Will try and take a look at those now.

Seems to be IntellijJank but I'm unsure how to run these existing Codec tests.

Managed to hack something together to run the Codec serialization tests and they all pass.
