Add `library_name: transformers` to model card metadata

This PR improves the model card by adding the `library_name: transformers` metadata tag. The `config.json` file shows that the model is compatible with the `transformers` library, as indicated by `"transformers_version": "4.42.0.dev0"`.

Adding this tag will enable the automated "How to use" widget on the model page, providing users with a convenient code snippet for loading and using the model with the 🤗 Transformers library.
