This PR improves the model card by:
- Adding the `image-text-to-text` pipeline tag to ensure the model is correctly categorized in the Hub.
- Adding `library_name: transformers` to enable the automated code snippet feature and "Use in Transformers" button.
- Providing a clear sample usage section based on the official documentation.
These changes will improve the model's discoverability and usability within the Hugging Face community.
