Following the recommendation from airbnb/lottie-ios#2371, this updates the NSPrivacyAccessedAPITypeReasons in our privacy manifest from:

3B52.1: Declare this reason to access the timestamps, size, or other metadata of files or directories that the user specifically granted access to, such as using a document picker view controller.

to:

C617.1: Declare this reason to access the timestamps, size, or other metadata of files inside the app container, app group container, or the app’s CloudKit container.
