Lots of small tweaks

- Gave nicknames to the Galar Evolution trades, they're a bit different to regional variants n such
- The Throw Rock command now only increases flee chance by 50%. It seems like it may be a little TOO strong though, bit curious.
- Changed a bit of text here and there
- Made CHIKUCHIKU trade accessible, still need MICHELLE
