This is intended to reduce user errors where e.g. someone uses the
1.19 jar on 1.19.2. Previously this would lead to unspecific mixin
errors; with this change, a helpful message is shown:
Mod 'Dynmap' (dynmap) 3.4-SNAPSHOT requires version 1.19 of 'Minecraft' (minecraft), but only the wrong version is present: 1.19.2!
