Add client support for the organization overview endpoint

[BastienGimbert]

Problem

I needed to pull full organization metadata (description, avatar, stats, etc.) for a feature, but the Python client had no helper hitting /api/organizations/{org}/overview.

Summary

• add an HfApi.get_organization_overview helper hitting /api/organizations/{org}/overview
• surface the extra org metadata (avatar, description, counts, etc.) through the Organization dataclass
• export the new helper at the package root and validate it with a production UserApi test

Testing

• python -m pytest tests/test_hf_api.py -k organization_overview

Hi @hanouticelina,
I removed the id field.
I didn’t change the comment for token because the other comments don’t use ** or ``.
I kept the same style.

There are 106 other lines that only use token (Union[bool, str, None], optional)

@BastienGimbert thanks for noticing! I updated the parameter docstring in main and pushed f929cf8 to align the PR.

All good on my side, let's wait for a final approval from @Wauplin before merging!
