[iOS] Fix ScrollView detection when used with NativeDetector

[j-piasecki]

Description

Our check for ScrollView was checking for RCTScrollViewComponentView, but inside NativeDetector, we extract contentView from RCTViewComponentViews:

react-native-gesture-handler/packages/react-native-gesture-handler/apple/RNGestureHandlerDetector.mm

Lines 298 to 303 in 08c46d8

	if ([view isKindOfClass:[RCTViewComponentView class]]) {
	RCTViewComponentView *componentView = (RCTViewComponentView *)view;
	if (componentView.contentView != nil) {
	view = componentView.contentView;
	}
	}

And it so happens that RCTScrollViewComponentView inherits from RCTViewComponentView, which broke the ScrollView detection. The contentView of RCTScrollViewComponentView is RCTEnhancedScrollView.

Test plan

ScrollView from RNGH should now correctly delay touches on native buttons.
