Add FishHookStateChangeEvent to detect fishing hook state transitions.

[NamiUni]

Currently, PlayerFishEvent is not triggered when a FishHook changes its state. This means that if you want to track state transitions, you have to monitor them using a scheduler, which is inefficient. To address this, I have implemented FishHookStateChangeEvent.

• This event is useful when you want to send messages, titles, or sounds to players based on fishing hook state transitions.
• Canceling the transition to HookState.BOBBING prevents Minecraft#FishingHook#catchingFish from executing.
• Be cautious when handling this event, as canceling it will not prevent the state transition from being re-evaluated in the next tick. If the conditions are still met, the event will be instantiated and called repeatedly. (This behavior is documented in the Javadoc.) Reverted due to spamming of events and desync with the client side.

For consistency, this event is mostly copied from PufferFishStateChangeEvent. However, I feel that "State Transition" might be a more appropriate term than "State Change."

After re-testing, I confirmed that everything works perfectly. If nothing has been overlooked, then this should be complete👍
