Add auto-generation of settings to the documentation

Description

We should generate adoc file based on the ConfigRoots.
This will be available in the next quarkus release, see: https://github.com/quarkusio/quarkus/pull/8994#issuecomment-624233829

Once the settings file is generated, it should be included in the main doc file:
