This PR improves the model card by adding relevant metadata:
- Sets the `pipeline_tag` to `robotics` to ensure the model is correctly categorized on the Hugging Face Hub.
- Specifies the `license` as `other` to reflect the custom NVIDIA license.
- Adds a BibTeX citation section for the paper "Cosmos Policy: Fine-Tuning Video Models for Visuomotor Control and Planning".
- Maintains existing links to the paper, project page, and code repository.
