few raptor taming minigame difficulty tweaks (#89925)

## About The Pull Request
ive heard from a few players that the game is a bit too difficult,
especially when there's lag. this makes the minigame generally much
easier, and takes ping into account. ive also made the difficulty depend
on a few factors:

- the raptor's personality affects the difficulty, where raptors with
the cowardly trait will be slightly harder to tame
- Settlers will have a much easier time taming raptors

(ive also moved the minigame into its own file)

## Why It's Good For The Game
the game was a bit too unforgiving, this makes it easier for people to
win. And the dynamic difficulty gives the feature some personality.

## Changelog
🆑
add: tweaks the raptor taming minigame to be fairer 
add: the taming minigame's difficulty now relies on the raptor's
personality as well as the rider's quirks
