Add task category, code link, and remove arXiv tag from metadata

This PR adds the missing `task_categories: other` field to the YAML metadata so the dataset is properly categorized on the Hub. It also removes the `arxiv:` tag from the metadata (the arXiv paper is already linked in the Markdown content), and adds a link to the GitHub code repository in the header.
