Add task category: robotics

This PR adds the `task_categories: ['robotics']` metadata to the dataset card.

The paper abstract and the "Recommended for" section in the dataset card itself highlight the dataset's applicability to "robotics embodied AI tasks," "physical manipulation and navigation," and "pretraining vision-action models for transfer to embodied AI (robotic manipulation, navigation)." Adding this metadata will improve the dataset's discoverability on the Hugging Face Hub for researchers in the robotics domain.
