Add pipeline_tag and improve model card metadata

Hi! I'm Niels from the community science team at Hugging Face.

This PR improves the model card for MedCLIPSeg by:
- Adding `pipeline_tag: image-segmentation` to the YAML metadata for better discoverability.
- Refining the tags to follow Hub standards.
- Adding the author list and a concise summary of the model's purpose.

The technical details and reproduction steps remain unchanged. Thanks for sharing this research with the community!

+MedCLIPSeg is a vision–language framework for **medical image segmentation** built on top of **CLIP**. It adapts CLIP for robust, data-efficient, and uncertainty-aware segmentation through probabilistic cross-modal attention and bidirectional interaction between image and text tokens.
 
 The released checkpoints correspond exactly to the experiments reported in our paper and are provided **for evaluation and reproducibility purposes only**.
