[build.gradle.kts] kotlinOptions is deprecated

[hamoid]

'kotlinOptions: KotlinJvmOptions' is deprecated. Please migrate to the compilerOptions DSL. More details are here: https://kotl.in/u1r8ln

Deprecated:

tasks.withType<KotlinCompile> {
    kotlinOptions.freeCompilerArgs = listOf("-opt-in=kotlin.RequiresOptIn")
}

Updated but not tested:

import org.jetbrains.kotlin.gradle.tasks.KotlinCompilationTask

tasks.named("compileKotlin", KotlinCompilationTask::class.java) {
    compilerOptions {
        freeCompilerArgs.add("-opt-in=kotlin.RequiresOptIn")
    }
}
