This PR significantly improves the model card for the TokenBridge model by:
- Adding the `pipeline_tag: text-to-image` metadata, ensuring the model can be found at https://huggingface.co/models?pipeline_tag=text-to-image.
- Including a link to the official project page: https://yuqingwang1029.github.io/TokenBridge/.
- Extending the model description with the paper's abstract and key highlights from the GitHub repository.
- Providing sample usage instructions for installation, reconstruction, and generation, directly from the GitHub README.
These updates make the model card more informative and user-friendly for researchers and practitioners.
