Codegen fails to detect language if Kotlin plugin is defined after codegen plugin

Code generation fails to detect Kotlin language if the Kotlin plugin is defined after the dgs.codegen plugin.

Doesn't work:

plugins {
    id("com.netflix.dgs.codegen") version "4.4.3"
    kotlin("jvm") version "1.4.31"
}

Works:

plugins {
    kotlin("jvm") version "1.4.31"
    id("com.netflix.dgs.codegen") version "4.4.3"
}

Symptoms

1. Codegen would generate Java classes instead of Kotlin
2. More importantly, the codegen task would depend on the Java compile task and thus would not be executed automatically on a Kotlin project

Reproduce the issue using the two Kotlin Gradle plugin orderings shown in the report, then inspect how the codegen plugin detects Kotlin and wires its task dependencies. Done means both orderings generate Kotlin classes and make code generation run automatically in a Kotlin project.
