Improve model card: update license, add tags, and HF paper link

This PR improves the model card for OS-Genesis by:

- Updating the `license` metadata from Apache-2.0 to MIT, aligning with the license specified in the official GitHub repository.
- Adding relevant `tags` to the metadata (`gui-agent`, `vlm`, `multimodal`, `web-navigation`, `android`) for better categorization and searchability on the Hugging Face Hub.
- Including an explicit link to the Hugging Face paper page (https://huggingface.co/papers/2412.19723) in the content section, alongside the existing arXiv link, to enhance discoverability within the Hub.
