Spawn Replacement - Slightly Wider Variety & Some Changes (Gen 8)

Allows a somewhat wider variety of Pokemon to spawn from certain, more common spawners. Such as the various kinds of zombie spawners, skeleton spawners, etc. Mainly made it because I use some dungeon structures with this mod (such as When Dungeons Arise) and just kinda, didn't feel much for the skeleton ship and pillager tower full of nothing but Cubone.

btw, this is more of an example datapack since i don't really see anyone else using this, so in case you didn't know, you can also apply this to modded mobs. so, basically, you can throw in your favorite structures with modded mobs (goblins and dungeons maybe) and just have the better spawner replace the modded mob with whatever you want!

Keep in mind that these configs may mess with mob farms, since, y'know, drops are different.

General fun additions:
Zombie/Skeleton spawners have a bigger variety of Pokemon.
Araquanids spawned from Spiders are "Microscopic"-sized (note: basically just spider height as opposed to being utterly massive)
Cubone/Marowak spawned from Strays know Icy Wind
Cubone/Marowak spawned from Zombies know Thief
Cubone spawned from Skeletons know Bone Club a lot earlier
Spider-pokemon spawned from Cave Spiders know a poison move. Admittedly I could've been more evil and just have everyone use Toxic, but nah.
Pokemon spawned from Creepers only know Explosion. Not sure if I'm gonna give 'em a second attacking move just to keep ghost-types on their toes.
Pre-evos of most Pokemon in these spawners (like Zombie spawners summoning Trubbish), but not sure if I'm gonna remove it or not since it might make dungeons too easy.
