Add robotics task category and update repository link

Hi, I'm Niels from the community science team at Hugging Face. I'm opening this PR to add the `robotics` task category to your dataset's metadata, which will help researchers find it more easily when filtering by task. I've also updated the GitHub repository link to point to the official organizational repository.
