fix: memory leak introduced in 21f7601

[DavidBertet]

Issue

• Self is accessed within AVCaptureEventInteraction closure
• The AVCaptureEventInteraction is stored in eventInteraction class variable
• This creates a retain cycle

react-native-camera-kit/ios/ReactNativeCameraKit/CameraView.swift

Lines 128 to 135 in 21f7601

	let interaction = AVCaptureEventInteraction { event in
	// Capture a photo on "press up" of a hardware button.
	if event.phase == .began {
	self.onCaptureButtonPressIn?(nil)
	} else if event.phase == .ended {
	self.onCaptureButtonPressOut?(nil)
	}
	}

Solution

Use [weak self] to break the cycle

How did you test this change?

• Launch App
• Open Camera 3 times

Before

• Observe leak, 3 instances of CKCameraView because of the closure
  

After

• No leak, closure doesn't retain anything
