[issue46976] Update macOS installer builds to use ncurses 6.3

[Ned Deily]

New submission from Ned Deily <nad at python.org>:

The python.org macOS installers include a private copy of the ncurses library; it has not been updated from 5.9 in a long time. The current upstream version is 6.3 and includes bug and security fixes; we should update to it.
