gh-101100: Fix Sphinx warnings in curses and curses.ascii modules

[hugovk]

Fix 118 nit-picky warnings in Doc/howto/curses.rst, Doc/library/curses.rst and Doc/library/curses.ascii.rst.

There are still a few remaining warnings I wasn't sure about, so they've not yet been removed from .nitignore, but it reduces 130 -> 12 warnings.
