Kotlin - jackson support in the asyncapi cli

[ahmetcetin39]

Why do we need this improvement?

As Kotlin user, would appreciate to have the jackson validation support on Kotlin language just like Java support (--javaJackson) so that we can use Kotlin generated classes rather than Java

How will this change help?

It will help Kotlin users to have validation on asyncapi generated models

Screenshots

No response

How could it be implemented/designed?

Having another flag in the asyncapi generate model to support Kotlin jackson, something like --kotlinJackson

Hi @derberg, are we planning to support this? I’d like to work on it if it’s available. Just wanted to confirm before I start.

@ahmetcetin39 makes sense but just fyi, CLI is a project that integrates different libraries that serve different goal. So asyncapi generate model uses https://github.com/asyncapi/modelina. Enabling --kotlinJackson is easy as long as modelina supports it

Hey@derberg ,

### My understanding:
Kotlin users currently don’t have Jackson-based validation support when generating models via the AsyncAPI CLI, unlike Java (--javaJackson). Since the CLI relies on Modelina for model generation, adding Kotlin Jackson support depends on Modelina exposing this capability.

### My approach:
I would like to first look into Modelina’s support for Kotlin + Jackson (related issue: #2398), and then wire that support into the CLI via a new flag (e.g. --kotlinJackson) if feasible. This would allow Kotlin users to validate generated models in the same way Java users can.

If this approach sounds reasonable, may I proceed with a PR?
