Documentation for annotations fields

Issue in /src/pages/guides/appbuilder-configuration.md

Hello,

As far as I can see there are in APP builder configuration file `app.config.yaml` there are some properties that do not have documentation explaining how to use them, for example:
- require-adobe-auth
- annotations/provide-api-key

Seems those are important ones but I can not find anything in the spec about them so it would be worth adding them to the docs.

Cheers,
Bartek

Read src/pages/guides/appbuilder-configuration.md and locate the configuration fields for require-adobe-auth and annotations/provide-api-key. Check the existing guide and any available App Builder configuration references to determine their usage, then document both properties with enough explanation for users to configure them.
