This PR enhances the dataset card for the `NICE` benchmark by:
* Adding `task_categories: ['text-to-image']` to the metadata for improved discoverability.
* Including an explicit link to the associated GitHub repository: https://github.com/mhson-kyle/World-To-Image.
* Adding a "Sample Usage" section with a Python code snippet from the GitHub README, demonstrating how to load the dataset using `load_dataset`.
