Leverage the use cases and knowledge of AuthConfig but with an AuthPolicy context

[maleck13]

** What **

There are many use cases covered by the Authorino docs using AuthConfig. AuthConfig is effectively a sub resource of the AuthPolicy. Ideally we would have a way to show how to solve these use cases using kuadrant's AuthPolicy. As AuthPolicy is a AuthConfig with policy attachment features. It should be possible to template a wrapper doc that calls out that the authconfig shown is effectively a drop in for the authentication section of the auth policy.

Outcome

using a new "Auth" template doc, under the Tutorials section, expand that to cover many of the common use cases outlined in Authorino https://github.com/Kuadrant/authorino?tab=readme-ov-file#use-cases to help the user understand what and how to achieve their auth requirements.
