Add pipeline tag and library name to SU-01 metadata

Hi there! I'm Niels from the community science team at Hugging Face.

This PR improves the model card for **SU-01** by:
1. Adding the `pipeline_tag: text-generation` to the YAML metadata for better discoverability.
2. Adding `library_name: transformers` as the configuration files indicate compatibility with the Transformers library.
3. Ensuring the associated research paper is linked in the Markdown content.

The rest of the comprehensive documentation provided by the authors, including the performance benchmarks and training details, has been preserved.
