Flyout does not support isOverlayEnabled when isLightDismissEnabled=true

Problem Description

When isLightDismissEnabled=false, isOverlayEnabled darkens the background, when light dismiss is true, the background is no longer darkened, if this is by design it should be mentioned in the API.

Steps To Reproduce

const { height, width } = useWindowDimensions();

<Flyout
isLightDismissEnabled={false}
isOverlayEnabled={true}
style={{ width: width, height: height }}
verticalOffset={height / 2}
horizontalOffset={width / 2}
pointerEvents={'auto'}
>
test

Start by reproducing the reported Flyout example with react-native-windows 0.71.20, comparing isOverlayEnabled with isLightDismissEnabled set to true and false. Inspect the Flyout implementation and its API documentation; done means the overlay behavior is corrected or the interaction is explicitly documented, with a regression check for both settings.
