Add pipeline tag and library name, link to code

This PR improves the model card by:
- adding a link to the Github repository
- adding a pipeline tag, ensuring it can be found at https://huggingface.co/models?pipeline_tag=image-text-to-text
- ensuring the model can be used using the appropriate auto classes of the Transformers library.
