Add pipeline tag, library name, and project page link

This PR adds the missing `pipeline_tag` and `library_name` to the model card metadata. The `pipeline_tag` is set to `image-text-to-text` given the model's functionality. The `library_name` is set to `open_clip` based on the provided code examples and file structure.
