[Web] Fix bottom hitslop (#3644)

## Description

Currently `hitSlop` on web uses `width` instead of `height` to calculate `bottom` property. This is incorrect.

Fixes #3633 

## Test plan

Trust our intuition 🤓 

<details>
<summary>Tested on the following example:</summary>

```jsx
import React from 'react';
import { StyleSheet, View } from 'react-native';
import { Gesture, GestureDetector } from 'react-native-gesture-handler';

export default function EmptyExample() {
  const gesture = Gesture.Pan().hitSlop({ bottom: -20 }).onUpdate(console.log);

  return (
    <GestureDetector gesture={gesture}>
      <View style={styles.box} />
    </GestureDetector>
  );
}

const styles = StyleSheet.create({
  box: {
    width: 10,
    height: 100,
    backgroundColor: 'red',
  },
});
```
