Update to AGPL-3.0 License

In this PR, we've updated the licensing of the YOLOv8 models on Hugging Face Spaces to AGPL-3.0 to comply with the original [Ultralytics YOLOv8](https://github.com/ultralytics/ultralytics) requirements for derivative works at. This essential change ensures this project remains transparent, accessible, and legally sound, fostering an environment of trust and collaboration within the open-source community.
