Add DevUI setup documentation steps

[LuboTerifaj]

The current documentation is missing steps how to properly configure DevUI in the project.

Chapter: https://sonataflow.org/serverlessworkflow/main/testing-and-troubleshooting/quarkus-dev-ui-extension/quarkus-dev-ui-overview.html

Issues

• Missing prerequisites (having project) for the following commands in quarkus-dev-ui-overview.html:

  • quarkus ext add org.apache.kie.sonataflow:sonataflow-quarkus-devui
  • quarkus ext add org.kie:kie-addons-quarkus-source-files

• Missing description of "kie-addons-quarkus-source-files" depdendency, what is its purpose in overview: quarkus-dev-ui-overview.html

  • It is described later in the documentation, in quarkus-dev-ui-workflow-instances-page.html)
  • It would be probably more readable to describe the dependency first, set up the environment, and then utilize its functionality.

• The following dependency is missing the necessary version to work properly:

<dependency>
  <groupId>org.apache.kie.sonataflow</groupId>
  <artifactId>sonataflow-quarkus-devui</artifactId>
</dependency>

• Missing prerequisite for running SonataFlow application with DevUI to access Dev UI in quarkus-dev-ui-workflow-instances-page.html
