3.x: archetypes generating poorly formatted code

[barchetta]

The 3.2.0 archetypes are generating poorly formatting source code due to changes made for #6269

To reproduce:

helidon init --version 3.2.0
# Accept all defaults to generate SE quickstart

Edit Main.java

Go to line 74 and see:

        SimpleGreetService simpleGreetService = new SimpleGreetService(config);        GreetService greetService = new GreetService(config);

Notice the missing newline.
