Improve model card: Add pipeline_tag, library_name, and update title

This PR enhances the model card for Reason-RFT by:
- Adding `pipeline_tag: image-text-to-text` to improve discoverability on the Hub.
- Adding `library_name: transformers` based on `config.json` and `tokenizer_config.json` showing compatibility. This will enable an automated "how to use" widget.
- Updating the main H1 title to reflect the paper and model name: "Reason-RFT: Reinforcement Fine-Tuning for Visual Reasoning of Vision Language Models".
- Removing the descriptive sentence below the previous title, as the new H1 title makes it redundant.

These updates aim to provide clearer and more structured information for users.
