Add `library_name: diffusers` to model card metadata

This PR adds the `library_name: diffusers` to the model card's metadata. This ensures that the automated "How to use" widget appears on the model page, showcasing compatibility with the Diffusers library for easier use by the community.

The model card already provides comprehensive information, including links to the paper, project page, and code repository, as well as clear inference instructions.
