Improve model card for RedDino-small: Update pipeline tag and add GitHub link

This PR significantly improves the model card for `RedDino-small` by:

- Updating the `pipeline_tag` from `feature-extraction` to `image-feature-extraction` for better discoverability and accuracy on the Hugging Face Hub. The redundant `feature-extraction` tag has also been removed from the general `tags` list.
- Adding a direct, prominent link to the GitHub repository (`https://github.com/Snarci/RedDino`) at the top of the model card for easier access to the source code and additional information.
- Setting the main title to the paper's title `# RedDino: A foundation model for red blood cell analysis` for better representation.
- Including the "Summary" section from the original GitHub README to provide a concise overview of the model's contributions and goals.

These changes enhance the model card's clarity, completeness, and adherence to Hugging Face Hub best practices.

 Notes:
-- Trained with RBC-specific augmentations and DINOv2 customizations (e.g., removal of KoLeo regularizer; Sinkhorn-Knopp centering).
-- Optimized using smear patches rather than only single-cell crops to improve generalization across sources.
