Get the starter to deploy to Open Liberty

[Emily-Jiang]

The current starter app was deployed to Thorntail, which was sunset a few years ago. We need to move to an active runtime. Open Liberty can be used for this purpose because the latest release supports both javax and jakarta namespace. After the move, we can update the namespace from javax to jakarta.
