Add paper link, GitHub repository, and improve metadata

Hi, I'm Niels from the Hugging Face community science team. I've updated the dataset card to improve its metadata and accessibility:
- Added the `arxiv` tag to the metadata to link the dataset to its research paper.
- Added direct links to the paper, project page, and official GitHub repository in the header.
- Fixed a typo in the tags (`webdatset` -> `webdataset`).
- Fixed a minor syntax error in the Python loading example (missing closing parenthesis).
- Standardized the citation format.

These changes will help researchers discover and use this dataset more effectively!
