Add task categories and update citation

Hi! I'm Niels from the Hugging Face community science team. I'm opening this PR to enhance the dataset card metadata and documentation:
- Added `task_categories: [other]` to the YAML metadata.
- Included the ArXiv identifier in the metadata.
- Updated the paper links and badges to point to the correct research paper page.
- Filled in the citation section with the appropriate BibTeX from the GitHub README.
- Added a GitHub badge for quick access to the code repository.
