Improve dataset card: Add task category, Github link, clarify license

This PR improves the dataset card by:

- Adding the `text-to-image` task category to the metadata.
- Adding a link to the GitHub repository.
- Clarifying the license for the dataset (assuming it's the same as the code, MIT, but this needs confirmation from the authors).
- Ensuring the paper link is correct.

Please confirm the license for the dataset. If it is different from MIT, please update the metadata accordingly.
