Added starter data for Gen 4-9, Legends Arceus, and Legends Z-A.
Fixed Yellow and Let's Go which were incorrectly aliased to the
firered-leafgreen Gen 1 trio — they now have their own entries.
Added aliases for Platinum, BD/SP, B2/W2, and USUM.

Gifts, trades, and fossils are already in the per-game encounter data.
Only starters need to remain in special_encounters.json. Updated the
corresponding bean to reflect the narrowed scope.
