NeoForge Platform Support (#3781)

* Initial work on Forge platform

* Rework modded platforms to use a common module

* Add support for integrated worlds on modded platforms

* Fix classload errors and move mixins to shared module

* Fix Fabric mixins and check min height in mod world manager

* Add Forge command support

* Add back modrinth publishing

* Don't apply application plugin to shared mod sources

* Fix docs

* Delete unused class

* Clean up repositories

* - Update to 1.20.2
- set custom refmap name
- fixed console commands crashing the server (hasPermission now accepts CommandSourceStack instead of Player)
- Forge wants fastutil relocated, so be it

Current issues:
- ClassNotFound exceptions with classes that are clearly present

* - Fix ClassNotFound errors on Forge due to weird Classloader
- Dont relocate gson

* merge upstream

* oh no

* Bump lombok, architectury-loom

* init: neoforge 1.20.4 support

* NeoForge builds

Signed-off-by: Joshua Castle <26531652+Kas-tle@users.noreply.github.com>

* Archive neoforge artifacts

* transformForge -> transformNeoForge

* Neoforge boots!
* Fix mixins on neoforge
* Update build/pr file names
* Update mods.toml to new neoforge standard
* Fix refmap naming

* more fixes
- no need to include gson
- cleanup nullable/nonnull annotations
- add more info to geyser dumps on neoforge

* yeet platform executor

* yet another temp branch to figure out the runServer task

* yeet transitive dependency, that cant be right

* Attempt at getting the runServer task to work, part two

* Revert the changes for the runServer task, try and shut down the injector

* Remove spigot weird bug workaround, shut down properly
Also add a compileOnly dependency for the mod module to get rid of spammy false warnings

* Update to latest restart changes
- fix duplicate nodes crashing neoforge
- connector -> geyser in GeyserModCommandExecutor
- create command manager early to fix issues with permission gather event

* Consistent NeoForge spelling, move some dependencies to the version toml

* Add lombok to version catalogue

* Add plugins to version catalogue

* revert move to buildSrc

* Create `assets/geyser/icon.png` to reference icon from a single file on standalone/neoforge/fabric

* add fabric permissions api to libs.versions.toml
