Update dataset card with robotics task, paper link, and usage

Hi! I'm Niels from the community science team at Hugging Face.

This PR improves the dataset card for the SCFields release by:
- Adding the `robotics` task category to the metadata.
- Linking the associated research paper: [Semantic-Contact Fields for Category-Level Generalizable Tactile Tool Manipulation](https://huggingface.co/papers/2602.13833).
- Adding a sample usage section with a training command found in the official repository.
- Including the BibTeX citation.
