Add robotics task category and sample usage instructions

Hi! I'm Niels from the Hugging Face community science team. I noticed the metadata for this dataset card was incomplete.

I've also included a "Sample Usage" section with download instructions using Git LFS, based on the documentation found in the project's GitHub repository.
