https://github.com/pypa/cibuildwheel/releases/tag/v2.17.0

This fixes the broken CI pipeline for macOS. https://github.com/mypyc/mypy_mypyc-wheels/actions/runs/8553233291/job/23435967050#step:4:74

PermissionError: [Errno 13] Permission denied: '/usr/local/opt/pipx'

This also addresses a warning in the actions output

While cibuildwheel can build CPython 3.8 universal2/arm64 wheels, we cannot test the arm64 part of them, even when running on an Apple Silicon machine. This is because we use the x86_64 installer of CPython 3.8. See the discussion in pypa/cibuildwheel#1169 for the details. To silence this warning, set CIBW_TEST_SKIP: "cp38-macosx_*:arm64".
