This PR significantly enhances the model card for DarkIR.
Key improvements include:
* Adding the `pipeline_tag: image-to-image` to improve discoverability on the Hugging Face Hub.
* Incorporating the paper abstract, a link to the Hugging Face paper page, and the GitHub repository.
* Including the Hugging Face Spaces demo link.
* Adding detailed installation instructions, datasets used, quantitative results, and sample inference commands directly from the project's GitHub README.
* Integrating the network architecture image and a gallery of qualitative results.
* Adding the BibTeX citation for proper attribution.
These updates provide a much more informative and user-friendly model card for the community.
