Subject: [PATCH] Fix regression with NativeSyntheticEvent and add test.
 (#38600)

Summary:
With moving the TypeScript declarations into the repo, the NativeSyntheticEvent type was copied incorrectly from DefinitelyTyped.

This was the old one: https://github.com/DefinitelyTyped/DefinitelyTyped/blob/master/types/react-native/v0.70/index.d.ts#L355

## Changelog:

[GENERAL] [FIXED] - Correct the NativeSyntheticEvent type

Pull Request resolved: https://github.com/facebook/react-native/pull/38600

Test Plan: Added a test and ran `yarn test-typescript`
