[tests] usage of setuptools' build-option passed as global-option

[stanislavlevin]

As of setuptools 69:

https://setuptools.pypa.io/en/stable/history.html#v69-0-0

Passing config_settings to setuptools.build_meta with deprecated
values for --global-option is no longer allowed. (pypa/setuptools#4066)

This leads to a test failure:

FAILED tests/integration/test_config_settings.py::test_config_settings_setuptools - subprocess.CalledProcessError: Command '['/tmp/pytest-of-runner/pytest-0/test_config_settings_setuptool0/venv/bin/python', '-m', 'pyproject_installer', 'build', '--backend-config-settings', '{"--global-option": ["--python-tag=test_tag", "--build-number=123", "--plat-name=test_plat"]}', '--outdir', PosixPath('/tmp/pytest-of-runner/pytest-0/test_config_settings_setuptool0/dist')]' returned non-zero exit status 1.
