Changelog:
[Internal] Rename AccessibilityInfo.sendAccessibilityEvent_unstable to sendAccessibilityEvent

In Fabric, we want people to use `AccessibilityInfo.sendAccessibilityEvent` instead of `UIManager.sendAccessibilityEvent` for Android. The API is not unstable. There is a test in [AccessibilityExample.js](https://github.com/facebook/react-native/blob/c940eb0c49518b82a3999dcac3027aa70018c763/packages/rn-tester/js/examples/Accessibility/AccessibilityExample.js#L959) in RNTester to confirm that it works.

A search for [`AccessibilityInfo.sendAccessibilityEvent_unstable` in Github](https://github.com/search?q=AccessibilityInfo.sendAccessibilityEvent_unstable&type=Code) shows that it's not being used yet, which makes sense because it's an Fabric API. Therefore it's safe to rename it.
