[no gbp] Reduces click cooldown of more primarily player-controlled mobs (#78686)

## About The Pull Request

Fixes #78679
We made a change to synchronise mob attack speed when controlled by
players and when controlled by AI but this ended up reducing the attack
speed of a few mobs which are primarily controlled by players. This
wasn't meant to be a balance change, so we should revert it for those
mobs.
People can use it as a balance lever later if they want (preferably
after Swing Combat is merged).

## Changelog

🆑
fix: Spiders, Morphs, Fire Sharks, and Regal Rats no longer have a
reduced click speed.
