Improve model card: add robotics pipeline tag, paper link, and repository details

This PR improves the model card for the GeneralVLA-2 model assets. It adds the `robotics` pipeline tag to the metadata to make it more discoverable under the robotics category. It also provides links to the official paper, project website, and GitHub repository, preserves the repository layout structure, and adds a BibTeX citation.
