YetAnotherConfigLib 3.0.0-beta.2+1.19.4

This version adds no features, nor bug fixes, instead it implements a breaking change:

The YACL package has changed to dev.isxander.yacl3 and the YACL mod-id has changed to yet_another_config_lib_v3.
This is to prevent conflicts with 2.0, so you can load both versions at the same time so older mods don't break.
