update mongodb panache docs with annotationProcessor info

Closes #24637

[gsmet]

I added some small suggestions.

Thanks for using the tabs :).

@gsmet what about MongoDB with Panache on Kotlin (https://quarkus.io/guides/mongodb-panache-kotlin)? Is there anything that needs to be updated there? I don't have much familiarity with Kotlin and don't know whether or not this annotation processor thing should be applied there too.

[edeandrea]

I also updated based on your suggestions @gsmet . I rebased back to a single commit as well.

Your guess is as good as mine :).

Thanks @edeandrea the same should be done for Hibernate ORM with Panache and Hibernate Reactive with Panache as they also need the annotation processor.

@loicmathieu I just submitted #26435 to add the same documentation for Hibernate ORM with Panache & Hibernate Reactive with Panache.

I'm still unsure if it should be added to the Kotlin variants as well.
