Python: Fix onnx pkg by pinning. Pin openai < 2.0. (#13284)

### Motivation and Context

For the latest onnxruntime 1.23.2 pkg: our GitHub Actions run is failing
because uv is not matching the macOS wheel tag.
Pinning to last-known-good until it's sorted out.

- Pin openai pkg < 2.0 until we can investigate if 2.0 brings in other
breaking changes.
