[1.21.4] NeoForge data generation remains broken due to conflicting modules

[Fuzss]

Architect Plugin: 3.4.161
Architectury Loom: 1.9.426
Minecraft: 1.21.4
NeoForge: 21.4.86-beta

Architectury Loom is up-to-data with #258 already merged.
Now setting up data generation for NeoForge using clientData() generates the following error:

Exception in thread "main" java.lang.module.ResolutionException: Module neoforge contains package net.neoforged.neoforge.internal.versions.neoform, module neoforge._21._4._86.beta.minecraft.merged.a422b5828a exports package net.neoforged.neoforge.internal.versions.neoform to neoforge

Both modules and package mentioned in the error are different on almost every launch.

The error was produced using Architectury Templates updated for Minecraft 1.21.4.
