Added missing tests for onHoverOut in Pressability (#55378)

Summary:
This PR adds the missing tests for the `Pressability` class, specifically for the `onHoverOut` property.
The tests simulate interactions similar to the existing `onHoverIn` tests, triggering `onMouseEnter` followed by `onMouseLeave` to verify that `onHoverOut` is called correctly.

## Changelog:

[General] [Added] - Added tests for `Pressability` `onHoverOut` property

Pull Request resolved: https://github.com/facebook/react-native/pull/55378

Test Plan:
- Ran the full React Native test suite to ensure all tests pass.
- Verified that the tests fail if the production code for `onHoverOut` is removed, confirming their effectiveness.
