Improve model card: Add library, pipeline tags, paper link, and GitHub link

This PR enhances the model card for SciReasoner 8B by adding crucial metadata and improving content clarity:

- **`library_name: transformers`**: The model is compatible with the `transformers` library, which enables an automated code snippet on the Hub, as evidenced by `config.json` (e.g., `"architectures": ["Qwen3ForCausalLM"]`, `"model_type": "qwen3"`).
- **`pipeline_tag: text-generation`**: This tag helps users discover the model for its described capabilities in "unconditional and conditional sequence generation and design" as per the paper abstract.
- **`tags: ['qwen', 'scientific-reasoning']`**: Adds relevant tags based on the model's architecture (`Qwen3ForCausalLM`) and its primary purpose as a "scientific reasoning foundation model."
- **Paper Link**: The official Hugging Face paper link ([SciReasoner: Laying the Scientific Reasoning Ground Across Disciplines](https://huggingface.co/papers/2509.21320)) has been explicitly added to the introductory text for direct access. The existing arXiv badge is retained.
- **GitHub Link**: An explicit link to the GitHub repository (`https://github.com/open-sciencelab/SciReason`) has been added for easier access to the associated code and evaluation scripts.

These updates improve the model's discoverability and provide users with clearer, more direct access to essential information.
