Add Custom Mob Spawner for version 1.12.2

Currently the Mo'Creatures Mod is impossible to put because the Custom Mob Spawner (A fundamental mod for this) is outdated for version 1.12.2. However, this is only on the Curse Forge page, being that in other pages the Custom Mob Spawner is available for version 1.12.2. So I only request that you take these reference pages to be able to use this mod on the Aternos servers. Thank you very much for your attention.
