Better metadata on java/quarkus template

[matzew]

I guess a bit similar to #1459

But in the quarkus template I see also some static information, which may be nice to make more dynamic:

• https://github.com/knative/func/blob/main/templates/quarkus/cloudevents/pom.xml#L5-L6
• https://github.com/knative/func/blob/main/templates/quarkus/cloudevents/src/main/java/functions/Function.java#L1

I've currently created a few projects, with the quarkus/template template and have now to change all of them, to have more reasonable maven artifacts
