Attribution required when adopting/forking AIPs

[rofrankel]

The google.aip.dev repo licenses its AIP content under the Creative Commons Attribution 4.0 License. This means that anyone forking the AIPs has to include a notice on just about every page along the lines of "This page contains content that was modified and/or reproduced from work created or shared by Google and used according to the terms in the Creative Commons Attribution 4.0 License."

The simplest way to do this, currently, is to fork the site generator and modify the site footer to add a generic notice like the one above. A better way to do this, not requiring a site generator fork (e.g. a footer.yml in google.aip.dev), would be great.

Example wording would also be great, so that forkers don't have to consult their companies' legal departments.

I'd argue we support overrides (e.g. footer.yaml) so that people don't have to fork. Forking is going down a quite unmaintainable path.
