Fix broken external documentation links to Ansible cloud provider guides

What does this MR do?

Ansible appears to have sunset the cloud provider guides we've used to reference auth methods for GCP and Azure in the Configure documentation, and they are now "Legacy Cloud Provider Guides".

Guides for using public clouds are moving into collections. We are migrating these guides into collections. Please update your links for the following guides:

Unfortunately GCP + Azure (the two sections where links broke) don't have the new Scenario Guide piece in their collection page like AWS does, so for now I just pointed the links back to the last available version of the links we've been using. (Version 9).
