Fix link plugins failing on Kotlin 2.4 projects

[wellingtoncosta]

Summary

Projects using co.touchlab.crashkios.crashlyticslink or co.touchlab.crashkios.bugsnaglink fail during Gradle configuration with Kotlin 2.4.x:

java.lang.NoClassDefFoundError: org/jetbrains/kotlin/gradle/targets/native/tasks/artifact/KotlinArtifactsExtensionKt
    at co.touchlab.crashkios.CrashlyticsLinkPlugin$apply$1$1.execute(CrashlyticsLinkPlugin.kt:35)

Kotlin 2.4 removed the experimental kotlinArtifacts DSL, which was deprecated in Kotlin 2.2 and became an error in 2.3. Both plugins still accessed project.kotlinArtifactsExtension inside afterEvaluate, causing configuration to fail because the API no longer exists.

Fix

Removed the kotlinArtifacts handling (crashLinkerConfigArtifacts) from both plugins.

The project's Kotlin version remains unchanged to preserve compatibility with older Kotlin 2.x versions.

I was able to reproduce the error on a sample project with kotlin 2.4 and after applying the fix it works. LGTM!
