Add `library_name: transformers` to metadata

This PR adds the `library_name: transformers` metadata tag to the model card. This will enable the automatic display of the "how to use" widget on the model page, providing users with a quick and easy way to interact with the model using the `transformers` library.

The existing model card is comprehensive and well-structured, requiring no further content modifications.
