summary:

Improve threading.daemon docstring (GH-14278)


Rephrase and clarify that "the entire Python program exits when only daemon threads are left". This matches the documentation at https://docs.python.org/3/library/threading.htmlGH-thread-objects.
(cherry picked from commit bb110cc2ed81447fb48805f31146cf31323a8fc3)
