Revert "Change direction type" (#3876)

This reverts commit 3d5e298.

## Description

I have overlooked that result of using bitwise `OR` operator on
`Directions` is of type `number`. This caused CI to
[fail](https://github.com/software-mansion/react-native-gesture-handler/actions/runs/20177351781/job/57928739635#step:5:1).

Also, now I see that it didn't cover all cases, so reverting it makes
sense.

## Test plan

```tsx
const fling = useFlingGesture({
  direction: Directions.RIGHT | Directions.LEFT,
});
```
