[Balance] Change a few early gym teams

[Fontbane]

What are the changes the user will see?

• Prevents mons of the wave 20 Gym Leader from evolving in the wave 20 fight
• Teams changed for a few Gym Leaders accessible by wave 30 (aka the first gym fight), and Lenora

Leader	Biome	Old Team	Extra	New Team	Extra
Wave 20
Cheren	Plains
Cilan	Plains
Chili	Plains
Cress	Plains
Wave 30
Crasher Wake	Lake
Whitney	Metropolis
Norman	Metropolis
Larry	Metropolis
Wave 50+
Lenora	Meadow

Note: Pokémon in the "extra" column are not used in the first Gym Leader battle.

Why am I making these changes?

• Wake was very problematic due to being the only leader in Lake biome, and Magikarp at wave 30 is basically a coin flip between complete fodder or way too difficult. His Magikarp was replaced with Wooper from his in-game team.
• Whitney, while rarer, was also an issue as Girafarig and Miltank are both very powerful at wave 30. Girafarig is only used in rematch teams anyway. It was replaced with Jigglypuff (similar to Clefairy) and Aipom (gen 2 Normal-type, used in-game and fits her being a softball player) was added for a third slot.
• Larry's Komala was pushed off to a fourth slot so it wouldn't be a problem on wave 30 fights.
• Norman's Chansey was replaced with Zigzagoon, found on his Emerald team. Kecleon is found in his rematches and is fun to fight against imo.
• Patrat was moved from Cheren to Lenora so they could both have their ace from the main series.
• The Striaton trio were also problematic, between the wave 20 Basculin, the random chance of the monkeys evolving, and Chili's Heatmor
• Erika is also accessible on wave 30 via Tall Grass biome but isn't an issue and remains unchanged.

What are the changes from a developer perspective?
