[ios][macos] Fix center coordinate incorrect after pinch gesture
To changelog: Fixed incorrect center coordinate after pinch regression caused by edge insets fix (#14664). While working on #14664, missed to understand the logic used in ``` CLLocationCoordinate2D centerCoordinate = _previousPinchCenterCoordinate; mbgl::EdgeInsets padding { centerPoint.y, centerPoint.x, self.size.height - centerPoint.y, self.size.width - centerPoint.x }; self.mbglMap.jumpTo(mbgl::CameraOptions() .withCenter(MGLLatLngFromLocationCoordinate2D(centerCoordinate)) .withPadding(padding)); ``` Replacing this code by moveBy achieves the required translation. Fixes: #14977, #15082
