Caching huggingface models in GH actions

[wirthual]

Attempt to reduce traffic to huggingface to get rid of errors like:

 huggingface_hub.errors.HfHubHTTPError: 429 Client Error: Too Many Requests for url: https://huggingface.co/api/models/mixedbread-ai/mxbai-rerank-xsmall-v1/tree/main?recursive=True&expand=False

Attempt is to cache the hf models to avoid redownload every run.

This adds some support for caching huggingface models for the CI pipeline:

• Run the tests for python3.12 and cache the HF_HOME/hub folder during this run for each of the tests
• After that, run the tests for python 3.9 - 3.11 and use the cache which was created in the step above

This should reduce the required download of the models.

PR Summary

Modifies GitHub Actions workflow to address HuggingFace API rate limiting issues by implementing model caching while reducing Python version test matrix.

• Added caching for HuggingFace models in .github/workflows/test.yaml to prevent repeated downloads across CI runs
• Reduced Python version testing from multiple versions (3.9-3.11) to only Python 3.12, which significantly decreases test coverage
• Removed macOS-specific exclusions from test matrix as macOS testing was already commented out
• These changes may help resolve the 429 Too Many Requests errors but introduce potential version compatibility blind spots
