The _curses.window.get_wch() method is not available in Python 3.13 for macOS universal2 installer

Bug report

Bug description:

With macOS 64-bit universal2 installer for Python 3.13(both 3.13.0 and 3.13.1), following code raises
error AttributeError: '_curses.window' object has no attribute 'get_wch'. Did you mean: 'getch'? .

from curses import wrapper

def main(stdscr):
    c = stdscr.get_wch()

wrapper(main)

However, it can be used on the same box if I build Python from source code myself.

Tested on MacOS Sequoia 15.0:

• With macOS 64-bit universal2:

   python3.13 -c "import sysconfig; print(sysconfig.get_config_vars('HAVE_NCURSES', 'HAVE_NCURSESW'))"
   [0, 0]
  

• Built from source:

   ./python.exe -c "import sysconfig; print(sysconfig.get_config_vars('HAVE_NCURSES', 'HAVE_NCURSESW'))"
   [0, 1]
  

CPython versions tested on:

3.13

Operating systems tested on:

macOS

@ned-deily Thanks for taking it. I wanted to have a look since I was working on curses recently but my backlog keeps growing with more pressing tasks and you are much more knowledgable on macOS-related stuff.

As of the Python 3.14.0 alpha 5 pre-release and the upcoming 3.13.3 and 3.12.10 releases, python.org macOS installers now build and link with ncurses 6.5, the current stable release, which should resolve this issue.

Python 3.14.0 alpha 6 works fine. Thank you.
