Kogito images for supporting services should no longer download the runner jar from maven repository

Current way of building image of supporting services is to have a reference to the last snapshot runner jar of the application.

We should modify the way we build the image and rely directly on the kogito-apps repository.

That way we could:

1. Build the concerned project directly from kogito-apps
2. Build could be done as fast-jar which is much quicker
3. Build the image by including the `target/quarkus-app` folder and `target/quarkus-run.jar` file

This would also avoid us to have to update the runner jar references daily and make sure we always get the latest version.
