BIG changes to postgame island

- Properly adds Brunswick Grotto, as well as Celeste Hill Outside and Celeste Hill Cave
- Citrine City received a minor redesign, putting the path to Brunswick Trail more to the west
- Added complete event for Galarian Zapdos as well as an encounterable, but unfinished Galarian Moltres, so all 3 birds can currently be caught
