Improve model card: Add pipeline tag, library name, and license metadata

This PR enhances the model card by adding the following metadata to the YAML header:
- `pipeline_tag: robotics` to categorize the model for vision-and-language navigation tasks.
- `library_name: transformers` to indicate compatibility with the 🤗 Transformers library, enabling the automated "how to use" widget.
- `license: cc-by-nc-sa-4.0` to explicitly state the model's license in the metadata, aligning with the existing badge and project documentation.

No other content changes were made, adhering to existing badge displays and external resource links.

Please review and merge if these additions align with the model's details.
