doc: gsg: warn against using Python 3.13 on Windows

History seems to repeat itself and we need to momentarily discourage
folks to use Python 3.13 on Windows until windows-curses releases a
PyPI package that works with it.
See https://github.com/zephyrproject-rtos/windows-curses/issues/69

Fixes #81543.
