Improve model card: Add metadata (pipeline_tag, library_name, license) and update paper link

This PR enhances the model card for the `bytedance-research/DynamicCoT` model by:
- Adding `pipeline_tag: image-to-text` to improve discoverability for multimodal tasks on the Hub.
- Adding `library_name: transformers` to enable the automated "How to use" widget, as the model is compatible with the 🤗 Transformers library, evidenced by installation instructions and model configuration.
- Adding `license: other` to reflect the specific "Qwen RESEARCH LICENSE AGREEMENT" mentioned in the model card content, which is not a standard SPDX license.
- Updating the existing paper badge to link directly to the Hugging Face paper page: [Boosting Multi-modal Keyphrase Prediction with Dynamic Chain-of-Thought in Vision-Language Models](https://huggingface.co/papers/2510.09358).

Please review and merge if these improvements are in line with the model's details.
