This PR updates the model card by adding the `library_name: transformers` metadata tag. This is based on evidence from the `config.json`, `tokenizer_config.json`, `preprocessor_config.json`, and `generation_config.json` files, which indicate full compatibility with the Hugging Face `transformers` library.
Adding this tag will enable the automated "how to use" code snippet on the Hugging Face Hub, making it easier for users to quickly integrate and utilize the MUSEG model.
