Add this project to the awesome-harbor list

This is an outstanding project. I think it is a perfect candidate to add it to the https://github.com/container-registry/awesome-harbor.

It seems that it is not longer maintained, I got several issues with Harbor 2.3.x with this adapter, I ditched it for trivy. Looking forward for a anchore/grype scanner adapter in the future.
