Restructure JWT documentation

[ssarmokadam]

Current documentation of JWT is at https://devonfw.com/website/pages/docs/devon4j.wiki_devon4j.asciidoc_guides.html#guide-jwt.asciidoc . We can add JWT overview/concept in General section of documentation.
This documentation have link for Spring JWT starter and JWT in Quarkus. We need to check further if we can add more details or some code snippets in both of this section.
Spring JWT and Quarkus JWT should be linked to General section document and vice versa.

Hi @ssarmokadam ,

Can you explain what is the current benefit of the JWT-starter in devon4j? In the past I've used open libraries like https://github.com/auth0/java-jwt for working with JWT and that worked out quite easily with very less code.
I'm thinking if we could deprecate the JWT module in favor of a generic documentation for both spring quarkus and spring.

As always the website links are meanwhile broken (404). For many years I am suggesting to never put these links and use github links instead but this seems to be like fighting windmills. The link to the guide on github is this one:
https://github.com/devonfw/devon4j/blob/master/documentation/guide-jwt.asciidoc

I can give you a rationale:
There are always two aspects:

• authentication
• authorization

JWT is mainly authentication but via claims it typically also contains permissions/roles that have impact on authorization.
You need to integrate all this with spring-security and actually spring-security is rather a complex beast to get things done, secure and working smooth.
With devon4j we actually wanted to give projects a jumpstart so they do not have to bother about all these aspects and get the integration out of the box.
And we never implemented the JWT itself in devon4j (generation, validation, parsing, etc.).
For this we are using spring (spring-security-jwt and jjwt) already and https://github.com/auth0/java-jwt is just an alternative implementation of it.

What I do not understand is what is actually missing to be addressed by this issue?
I can find all the things properly documented and would actually close this issue.
If someone can give a concrete aspect what is missing or to be improved, we can proceed.
Otherwise, I will simply close this issue in the next weeks.
