This PR improves the dataset card for the BEHAVIOR Robot Suite (BRS) Data by:
* Adding a "Sample Usage" section with practical code snippets for training a WB-VIMA policy and deploying it on a real robot, extracted directly from the project's GitHub README.
* Updating the "Demo" label under "Dataset Sources" to "Project page" for improved clarity and consistency with standard conventions.
* Adding relevant `tags` to the metadata (`robot-manipulation`, `imitation-learning`, `real-world-data`) to enhance the dataset's discoverability on the Hugging Face Hub, reflecting its core aspects as described in the paper and repository.
