This PR enhances the dataset card for ENACT by:
- Adding `image-text-to-text` to `task_categories` to better reflect the dataset's input/output format, alongside the existing `visual-question-answering`.
- Including `robotics` and `embodied-cognition` in the `tags` for improved discoverability, aligning with the paper's focus.
- Adding a direct link to the Hugging Face paper page (`https://huggingface.co/papers/2511.20937`) at the top of the content.
- Replacing the generic "Usage" section with a detailed "Sample Usage" section, featuring CLI commands for data download and evaluation directly from the GitHub repository, offering a clearer guide for users.
- Updating the BibTeX citation to include the `journal` and `year` fields, making it more complete as found in the GitHub README.
