Migrating built-in Shortcuts integration to iOS 13 APIs

Some news from Twitter:

PSA: The built-in Shortcuts integration for Pythonista will be removed early next year. I‘m working on integrating the new iOS 13 APIs, and I hope to have it ready by the end of the year. Migration might be automatic, but I‘m not sure about that yet.
