Update dataset card with paper link, task categories, and citation

Hi! I'm Niels, part of the community science team at Hugging Face.

This PR improves the dataset card for AgentSearchBench-Agents by:
- Adding `text-retrieval` to the YAML metadata `task_categories`.
- Linking the associated paper: [AgentSearchBench: A Benchmark for AI Agent Search in the Wild](https://huggingface.co/papers/2604.22436).
- Updating the BibTeX citation with the correct information from the repository.

Feel free to merge if this looks good!

 # AgentSearchBench Agents
 
 **AgentSearchBench** is a large-scale benchmark for AI agent search, built from nearly 10,000 real-world agents sourced from the [GPT Store](https://chatgpt.com/gpts), [Google Cloud Marketplace](https://cloud.google.com/marketplace), and [AgentAI Platform](https://agent.ai/).
