Improve dataset card: Add metadata and task category

This PR enhances the dataset card by correctly structuring the metadata. It moves the `license` and `language` fields from the Markdown content to the YAML front matter and adds `task_categories: text-ranking`, along with relevant tags for better discoverability. The paper link in the content has been formatted with its title, and a new section has been added to list other related datasets from the RAVine project available on the Hugging Face Hub, providing a more comprehensive overview for users.

 # RAVine-qrels
 
 The qrels in this repo refer to the relevance labels in MS MARCO V2.1 corpus for the queries of the RAVine test set. We collected them from [trec-2024-rag](https://trec.nist.gov/data/rag2024.html) and converted them into jsonline formats.
