bug: kotlin plugin wrapper not detected in module without version

Hello,

I use version 5.0.6 dgs codegen gradle plugin. And I have a project with two kotlin modules in it.

I applied the kotlin plugin in the root build.gradle.kts like that :

plugins {
    kotlin("jvm") version "1.5.30" apply false
}

And in my module like that :

plugins {
    kotlin("jvm")

In this situation the generateJava task in my module generate java classes and not kotlin classes.
Forcing 'language' in the GenerateJavaTask resolve the issue :

tasks.withType<com.netflix.graphql.dgs.codegen.gradle.GenerateJavaTask> {
    packageName = "org.example"
    language = "KOTLIN"
}

Importing kotlin("jvm") version "1.5.30" in each module also resolve the issue, but It's not recommanded.

Expected behavior

Kotlin classes generated without language = "KOTLIN" argument in GenerateJavaTask.

Actual behavior

Java classes generated.

Steps to reproduce

Create a module in a Kotlin project, in build.gradle.kts root apply kotlin plugin with version. In your module build.gradle.kts apply the kotlin module without version and generate some classes with generateJava task.

Reproduce the issue with a root build.gradle.kts declaring kotlin("jvm") with a version and a module applying it without one. Start with GenerateJavaTask and the generateJava task's language detection; done means the module generates Kotlin classes without explicitly setting language = "KOTLIN".
