Improve dataset card: Add associated papers, GitHub, project page links, and tags

This PR enhances the dataset card for Ultra-FineWeb by:
* Adding a link to the main MiniCPM4 paper ([https://huggingface.co/papers/2506.07900](https://huggingface.co/papers/2506.07900)), which describes the models trained using this dataset, and including its citation.
* Including a link to the associated GitHub repository ([https://github.com/openbmb/minicpm](https://github.com/openbmb/minicpm)).
* Adding a link to the MiniCPM4 Hugging Face collection ([https://huggingface.co/collections/openbmb/minicpm-4-6841ab29d180257e940baa9b)) as a project page.
* Adding descriptive tags (`llm`, `pretraining`, `web-corpus`, `data-filtering`, `high-quality`) for better discoverability.
