Description

Goal of this issue is to mark Keyboard module as unsupported for VisionOS.

As stated in Apple docs: https://developer.apple.com/documentation/uikit/uikeyboardwillshownotification?language=objc :

An app running in visionOS never receives this notification. The system displays the keyboard in a separate window, leaving the app’s window unaffected by the keyboard’s appearance and disappearance.

Goals:

• Avoid registering listeners inside RCTKeyboardObserver (#if TARGET_OS_VISION)
• Mark Keyboard and KeyboardAvoidingView as not supported
