Improve dataset card: Add paper and code links, refine metadata

This PR enhances the RSHR-Bench dataset card by:
- Adding a direct link to the associated paper: https://huggingface.co/papers/2512.17319
- Adding a link to the GitHub repository: https://github.com/Yunkaidang/RSHR
- Updating the `task_categories` in the metadata to `image-text-to-text` to better reflect the multimodal nature of the benchmark, which includes VQA and image captioning tasks.
- Adding comprehensive tags like `remote-sensing`, `mllm`, `vqa`, `image-captioning`, `high-resolution`, and `uav` for improved discoverability.
- Incorporating the news about the dataset's release on Hugging Face, as found in the GitHub README.
