Add pipeline tag, license and improve tags

This PR adds the missing `pipeline_tag` and `license` to the model card metadata. It also enhances the tags section for better searchability and categorization. The `image-text-to-text` tag reflects the model's ability to perform image classification with text-based explanations.
