[3.15] gh-139806: Mention pickle error changes in What's New in 3.14 (GH-154020) (GH-154161) The gh-122311 changes made pickle.dump() and pickle.dumps() raise PicklingError for some failures that previously raised AttributeError, ImportError, ValueError or UnicodeEncodeError, depending on the implementation. Add an entry about this in the "Porting to Python 3.14" section.
