This PR enhances the model card for the "Full-scale Representation Guided Network for Retinal Vessel Segmentation" model by:
* Adding the `pipeline_tag: image-segmentation` to improve discoverability on the Hugging Face Hub.
* Updating the `repository` metadata to point to the main GitHub repository (`https://github.com/ZombaSY/FSG-Net-pytorch`) and removing the redundant `github-link` tag.
* Including links to both the official Hugging Face paper page and the arXiv preprint for comprehensive paper access.
* Adding a clear link to the GitHub repository within the content section for code and usage instructions.
* Providing a concise summary of the paper's contribution.
* Including the experimental results table for quick reference on model performance.
* Adding the official BibTeX citation.
* Directing users to the GitHub repository for detailed setup and usage instructions, rather than duplicating extensive content.
Please review and merge if these updates are satisf…
