This PR improves the model card for the VideoLights model by:
- Adding `pipeline_tag: video-text-to-text` to enhance discoverability on the Hugging Face Hub under the correct pipeline filter.
- Adding relevant `tags: video-understanding, highlight-detection` for better categorization.
- Adding explicit links to the paper (Hugging Face and arXiv) and the GitHub repository at the top of the model card.
- Shortening the abstract to adhere to best practices of model card conciseness and avoid redundant information.
Please review and merge if everything looks good.
