Remove UIGestureRecognizerDelegate сonformance from ASCollectionNode to avoid MainActor Inheritance.

The current implementation of `ASCollectionNode` conforms to `UIGestureRecognizerDelegate`, which in turn inherits `MainActor`
```
@interface ASCollectionNode : ASDisplayNode <ASRangeControllerUpdateRangeProtocol, ASRangeManagingNode, UIGestureRecognizerDelegate>
```
