Fixes errors like
Modules MixinExtras and mixinextras.neoforge export package com.llamalad7.mixinextras.sugar.impl.ref to module just_blahajand
Module mixinextras.neoforge contains package com.llamalad7.mixinextras.lib.antlr.runtime.misc, module MixinExtras exports package com.llamalad7.mixinextras.lib.antlr.runtime.misc to mixinextras.neoforgeSpecifically if the error mentions BOTH MixinExtras and mixinextras.neoforge this should fix the problem.
Note this error will not appear in the latest.log on 1.18.2 and 1.19.2, and instead will only appear in launcher log files, so other symptoms that can indicate this is the log cutting off after the [net.minecraftforge.fml.loading.moddiscovery.JarInJarDependencyLocator/]: Found 3 dependencies adding them to mods collection line on versions older than 1.20.1.
This fixes the error by including an empty MixinExtras NeoForge jar, and a full MixinExtras forge jar. This ensures that only the Forge jar tries to load, preventing the error with both a full NeoForge and full Forge jar loading.
