Add robotics pipeline tag and license metadata

Hi! I'm Niels from the Hugging Face community science team. I've updated the model card to improve its visibility and metadata on the Hub:
- Added `pipeline_tag: robotics` so users can find this model when filtering by task.
- Added `license: other` to represent the custom NVIDIA One-Way Noncommercial License mentioned in the documentation.
- Added the BibTeX citation for the Cosmos Policy paper.

These changes help researchers and developers discover and cite your work more easily!
