Improve model card: Add pipeline tag, library name, paper/code/project links, and citation

This PR improves the model card for PersonaLive! by:
- Adding `pipeline_tag: image-to-video` to the YAML metadata to correctly categorize the model and enhance discoverability on the Hugging Face Hub.
- Adding `library_name: diffusers` to the YAML metadata. This enables the automated "how to use" code snippet, as the model demonstrates compatibility with components often used in the Diffusers library (e.g., `sd-image-variations-diffusers`, `sd-vae-ft-mse`).
- Adding explicit links to the paper ([PersonaLive! Expressive Portrait Image Animation for Live Streaming](https://huggingface.co/papers/2512.11253)), the code repository ([GitHub](https://github.com/GVCLab/PersonaLive)), and the project page ([huai-chang.github.io](https://huai-chang.github.io/)) at the top of the model card content for easier access.
- Uncommenting and correctly displaying the BibTeX citation section, which was present but hidden in the original model card.

Please review and merge this PR if everything looks good.
