Improve model card: Add Tequila paper, code link, and metadata

This PR improves the model card for the AngelSlim project, highlighting the Tequila quantization method.

Key updates include:
* Adding the `pipeline_tag: text-generation`, `library_name: transformers`, and `license: apache-2.0` to the metadata for better discoverability and automated usage snippets.
* Extending the `tags` to include `tequila`, `quantization`, and `ternary-quantization`, in addition to the existing `hunyuan`, `eagle3`, `eagle`.
* Adding an introductory section with a direct link to the "Tequila: Trapping-free Ternary Quantization for Large Language Models" paper and its specific implementation code within the AngelSlim GitHub repository.

These changes enhance the information available for the project and its artifacts.
