DeprecationWarning: 'asyncio.iscoroutinefunction' is deprecated

[hroncok]

Hello,

when building dependent packages in Fedora with Python 3.14.0a1, I got this when building meson-python:

____________________________ test_invalid_build_dir ____________________________

package_pure = PosixPath('/builddir/build/BUILD/python-meson-python-0.17.0-build/meson_python-0.17.0/tests/packages/pure')

mocker = <pytest_mock.plugin.MockerFixture object at 0x7f1b7d91b750>

    @pytest.mark.skipif(
        sys.version_info < (3, 8),
        reason="unittest.mock doesn't support the required APIs for this test",
    )

I just thought I send you a heads-up. It seems inspect.iscoroutinefunction is available since Python 3.5, so that should be safe to use. Will check.
