Port to 1.20

[OpenBagTwo]

What's Working

• The mod builds, and Minecraft loads with it and BCLib 3.0.2
• I can create a world without crashing
• I can construct an Eden Portal

  
• I can travel to the Eden Ring

  
• I saw a discwing (didn't grab a screenshot :disappointed:)
• Eden ring items show up in the creative inventory

What's Not

• There's no Eden Ring tab
• The Eden Ring guidebook is barely legible

  

What I haven't tested

• Crafting
• Mining / block breaking (see below)
• Multiplayer
• Anything having to do with gravity manipulation

What to Pay Extra Attention to

The most non-obvious changes (read: the ones I probably got wrong) were:

• rewriting the guide book rendering (and I clearly messed that up pretty badly, haha!)
• migrating to the tag-based system of determining which tools break which blocks, explicitly the portion of the program that determines what items are mineable by what. I followed BetterEnd's example, but I was stumbling around in the dark and have no idea if I did it right, or whether I was even matching intent when it came to hammer-compatibility.

Thank you so much for creating this gorgeous mod--there's nothing like spending a day and a half poring over someone's codebase to make you appreciate the impressiveness of their body of work. If there's anything I can do to assist in the future development of this mod (including sponsoring its development via KoFi, Patreon, etc.), please let me know.

Also thank you to @Treetrain1 (whose review, testing and feedback I would greatly appreciate!) for all the work on getting the mod to 1.19.3 (especially the datagen gradle task!)

Ha! Okay, update: placing a gravity compressor crashed the game:

java.lang.IllegalArgumentException: Cannot get property class_2746{name=extended, clazz=class java.lang.Boolean, values=[true, false]} as it does not exist in Block{edenring:gravity_compressor}

I'm guessing there's a problem with the piston a mixin...

Anyway, this is why this PR is likely to need a bit more attention than, say, #61

I'm closing this PR, as any port to 1.19.4+ really should be using the new tags system. I may try again, starting from @Treetrain1's 1.19.3 port, but I don't think I'll be reusing much of my own work from this PR.
