Add pipeline tag, library name and project page URL

This PR adds the `pipeline_tag` and `library_name` to the model card for better discoverability and clarity. The `pipeline_tag` is set to `image-to-image` reflecting the model's functionality of rendering images from triangle meshes, and `library_name: pytorch` is added given the model's implementation. The project page URL is added for easier access to further information about the project.
