Resolve noxfile.py conflict: Add polars version parametrization

- Add POLARS_VERSIONS = ["0.20.0", "1.32.2"] constant
- Update _testing_requirements to accept polars parameter
- Modify polars handling to use parametrized version: polars=={polars}
- Rename EXTRA_PYTHON_PYDANTIC to EXTRA_PYTHON_PYDANTIC_POLARS
- Add polars-specific test parametrization for multiple polars versions
- Update tests function signature to include polars parameter

This resolves the merge conflict with upstream/main regarding polars
version handling and testing parametrization.
