Automatically add dependency for jackson-module-kotlin

As pointed in the Kotlin documentation: https://quarkus.io/guides/kotlin#kotlin-and-jackson

The jackson-module-kotlin has to be manually added when there is the need to register the Kotlin module on Jackson, basically, when using kotlin + jackson.

Description When bootstrapping an application, when any Jackson specific extensions were added (as mentioned in the documentation above), with combination with quarkus-kotlin, then jackson-module-kotlin might also be automatically added as a dependency.

It may be simple for someone already in touch with Quarkus code to add this, I can try to do it myself otherwise, with some directions of any team member.

this should not be limited to code.quarkus.io - this should behave consistently across our tool chain.

do we have examples on other similar implicitly needed dependencies (that users must add and we can’t add for them elsewhere) ?

wondering if we should add a metadata to extensions to act as hint what could be recommended to add.

Thanks for pinging me! Indeed the lack of automatcally controlling additional dependencies has been bothering me for a while, and I believe the time could be right. I’ll send a proposal to the list.
