Every PR

(1) When the release CIs will run:
- After a PR has been merged into main/rel-* branch
- Run weekly (Sunday midnight) and publish Python wheel to onnx-weekly package on PyPI [2024.10.23: The current consideration is to delete the packages on pypi only due to running out of disk space. Starting with the oldest packages.]
- Any PR targeting rel-* branch
- To manually run them, add a PR label "run release CIs" (only maintainers have permission).
(2) Minimum supported versions are listed here.
(3) Test ONNX Python wheel with onnxruntime.InferenceSession from latest ONNXRuntime. Please note that ONNX Runtime does not support Windows-x86 thus its verification is skipped.
(4) Although the build environment is macos-11, use MACOSX_DEPLOYMENT_TARGET=10.12 and -p macosx_10_12_x86_64 to force the wheel to support 10.12+.
