chore(deps): Javax JSON to Jakarta JSON

Move to Quarkus 3.x Beta for updating to Jakarta version of the libraries. That means moving away from org.glassfish:java.json to jakarta.json:jakarta.json-api.

The new version will be released as v6.0.0. Any changes should go to both 5.x and 6.x versions until Quarkus 3.x is Final and javax.json is finally history.

Points:
- We might want to change the Import Order to include Jakarta.
- We might want to move from Javax to Jakarta for annotation, ws etc. in the examples.
