Add link to GitHub repos to container repo pages in Quay.io

[travier]

It would be nice to add the link to the project repos on GitHub with the sources to the description in the Quay.io container repo pages.

For example, for https://quay.io/repository/fedora/nginx-122?tab=info, the Description should link to https://github.com/sclorg/nginx-container.

Thanks!

This should be done by automation to automatically append new URL versions as soon as they are available and cross-check valid quay.io repositories. I tried to update some URLs while editing the documentation, and it was not a pleasant job. It would save a lot of hassle.
