Add pipeline tag and library name

This PR adds the `pipeline_tag` and `library_name` to the model card metadata for better discoverability and clarity. The `pipeline_tag` is set to `text-generation` as the model is a large language model capable of generating text. The `library_name` is set to `transformers` based on the file structure of the repository.
