Update pipeline tag, add library name, and add project/GitHub links

This PR improves the model card by:

- Updating the `pipeline_tag` from `question-answering` to `video-text-to-text` so the model is correctly categorized in the Hub.
- Adding `library_name: transformers` since the model is compatible with the Transformers library.
- Adding links to the project page and GitHub repository in the README.
