Nima custom archetype

fix #6243

[barchetta]

A couple things:

1. The READMEs say "JDK19+". Should say "JDK20"
2. quickstart-nima and custom-nima: the WebServer starts on a random port because application.yaml is not getting picked up. Had to add helidon-config-yaml to dependencies, and code to load config:

        Config config = Config.create();
        WebServer server = WebServer.builder()
                .config(config.get("server"))
                . . .

3. PR Fix archetype build #7177 broke CLI version 3.0.4. Can you fix the archetype build so that it creates both versions.xml AND cli-data/latest ? That way the archetype build works with either 3.0.4 or 3.0.5 CLI.
