Closes keycloak/keycloak#48291

Thank you for the PR to promote AuthZEN.

This blog post contains a lot of scripts and code, that then needs to be copied to files. It also seems a bit short on "What is AuthZEN?" and why "Why is AuthZEN better than any previous approach".

To draw more attention to it and encourage people to try it out, I suggest:

• Add more content why AuthZEN is the new star and what problems it solves better than any predecessors.
• Show evidence that there is a growing ecosystem that people can use it with
• Provide a diagram / image of some kind to draw attention to it
• Move the code to the Keycloak Playground to make it simpler for people to to try it out without copy and paste. It would also allow you to update it more easily as Keycloak nightly evolves.
• Keep only a minimal walkthrough without walls of JSON of the steps to give people the impression that it is simple and fun to use.
• Keep it short overall.

Thanks for the review @ahus1 @pruivo

I have updated the blog post so that all code is now contained in keycloak-playground: keycloak/keycloak-playground#29

Below is a screenshot of the included diagram as deploying keycloak-web locally results in the {blogImages} var being based upon keycloak.org.

LGTM, just have a couple of suggestions.
