Add pipeline_tag and library_name to model card

This PR improves the model card by adding the `pipeline_tag` and `library_name` to the metadata.

Adding `pipeline_tag: image-to-video` will ensure the model is discoverable through the Hugging Face Hub's pipeline filters (e.g., `huggingface.co/models?pipeline_tag=image-to-video`).
Adding `library_name: diffusers` will allow the "Use in Diffusers" widget to appear on the model page, facilitating easier usage for users familiar with the library. The model's usage instructions and dependencies clearly align with the `diffusers` ecosystem.
