WIP change Try play page example from starter project to tutorials

[rstento]

@dwijnand, @ignasi35, The objective of this is to change the recommended example (Follow the Hello World Tutorial) on the https://www.playframework.com/getting-started page to point to the correct Hello World Tutorial examples. In addition, I made some edits to simplify and clarify the page.

The changes I made look good when I build the web pages except, they do not display the links to download the Hello World Tutorials from Tech Hub:

No links appear here.

Maybe it needs to be live to pull in the links from the example-code-service? If not, could you take a look at the Application controller, I might have made a mistake while switching out the starters examples for tutorials. For your reference, on Tech Hub, the play-templates.conf file defines them like this:

tutorials = [
    {
      display-name = "Play Scala Hello World Tutorial"
      name = "play-scala-hello-world-tutorial"
      url = "git@github.com:playframework/play-scala-hello-world-tutorial.git"
      github-repo = "playframework/play-scala-hello-world-tutorial"
      branch = "2.6.x"
      keywords = [ "play", "scala", "tutorial", "hello-world", "2.6.x" ]
      "featured": {
        "play": 0
      },
      summary = "Play Hello World tutorial in Scala"
      description = "This tutorial introduces Play Framework, describes how Play web applications work, and walks you through steps to create page that displays a Hello World greeting."
    },
    {
      display-name = "Play Java Hello World Tutorial"
      name = "play-java-hello-world-tutorial"
      url = "git@github.com:playframework/play-java-hello-world-tutorial.git"
      github-repo = "playframework/play-java-hello-world-tutorial"
      branch = "2.6.x"
      keywords = [ "play", "java", "tutorial", "hello-world", "2.6.x" ]
      summary = "Play Hello World tutorial in Java"
      description = "This tutorial introduces Play Framework, describes how Play web applications work, and walks you through steps to create page that displays a Hello World greeting."
    }
  ]

Why target="_blank"?

Hi @dwijnand, Because if the reader wants to go read about Play and come back and try the examples, this way the page will still be open in their original tab. I've been doing a lot of documentation research lately and this is a common best practice when the link is supplemental information but the reader likely wants to come back and continue with the page.

OK, interesting :)
