fix: full window overlay cannot receive tap when modal is full screen (…

…#1872)

## Description
- `FullWindowOverlay` cannot receive tap events when it is shown on top
of `UIModalPresentationFullScreen` Modal which is the default
presentation style of the react native Modal.

- UIKit changes the layout hierarchy when the modal is full screen. It
is mentioned in the below docs. The view does not move to the window if
a full-screen modal is being presented. However, the `_container` moves
to the window as it is appended explicitly using `addSubview` in the key
window.

- So the `RNSFullWindowOverlay` view gets attached to the superview but
they are not moved to the window. This PR adds a simple fix to replace
`didMoveToWindow` with `didMoveToSuperview`. I considered an approach to
move `didMoveToWindow` in the `RNSFullWindowOverlayContainer` but I
don't see any potential issues with the current approach. Let me know.
