test_curses.test_use_default_colors fails on some platforms #132985
Description
Bug report
Bug description:
I'm pretty sure it's either my own configuration (openSUSE 15.5 + custom konsole) or my curses version (6.1) but here it is:
$ ./python -m test test_curses -ucurses

The cause
The current terminal fg/bg colors given by pair_content(0), which is backed by extended_pair_content(3), depends on the terminal emulator and its supported colors. Thus, its output cannot not be reliably checked.
