Add pipeline tag, library name, and link to code

This PR improves the model card by:
- Adding the `pipeline_tag: image-to-video`, which helps users discover the model via the Hub's pipeline filters (https://huggingface.co/models?pipeline_tag=image-to-video).
- Adding the `library_name: diffusers`, enabling the "how to use" widget on the model page.
- Adding an explicit link to the GitHub code repository.
