[Web] Remove hovering pointer from tracker. (#3115)

## Description

I've noticed that in `Hover` inside `onPointerMoveOut` method we add pointer to tracker instead of removing it. While it doesn't make much difference, since tracker is reset in [this line](https://github.com/software-mansion/react-native-gesture-handler/blob/b79223de5a47773a464543018b7231113c1ade68/src/web/tools/GestureHandlerOrchestrator.ts#L28), I think it will be better to change it into removing pointer.

## Test plan

Tested on `hover` example.
