Upgrade javax namespace to jakarta

[breakponchito]

The current implementation of the starter is still using old version of jakarta dependencies that use old javax namespace. We need to modernize the implementation to use latest version.

We need to get the starter on Open Liberty.

This one is blocked behind #500 . As the starter is deployed to Thorntail, which only supports javax, unless we deploy the starter app to Open Liberty, we cannot upgrade the namespace from javax to jakarta.
