This PR updates the dataset card to accurately reflect the VITA project, based on the paper [VITA: Vision-to-Action Flow Matching Policy](https://huggingface.co/papers/2507.13231).
Key changes include:
- Corrected the license in the metadata to `apache-2.0`, as indicated in the GitHub repository.
- Added `flow-matching` to the `tags` metadata to improve discoverability, given its presence in the paper title.
- Updated the `Paper` and `Homepage` links in the "Dataset Description" section.
- Added a `Code` link to the official GitHub repository: `https://github.com/ucd-dare/VITA`.
- Included a concise description of the dataset, derived from the paper's abstract.
- Added a comprehensive "Sample Usage" section, detailing environment setup, dataset preprocessing, and model training instructions, directly from the VITA GitHub README.
- Updated the BibTeX citation to the correct one for the VITA paper.
