Improve Kotlin binary compatibility

[igorwojda]

I am trying to use 13.0.0-rc01 with build-logic module storing convention plugins (used to encapsulate build logic and share module configuration across project).

The 12.2.4 works just fine, but when changing version to 13.0.0-rc01 gradle fails:

e: file:///Users/igorwojda/.gradle/caches/modules-2/files-2.1/com.mikepenz.aboutlibraries.plugin/aboutlibraries-plugin/13.0.0-rc01/975baa51ecdc2852925012899b39583b1993695f/aboutlibraries-plugin-13.0.0-rc01.jar!/META-INF/plugin.kotlin_module Module was compiled with an incompatible version of Kotlin. The binary version of its metadata is 2.2.0, expected version is 2.0.0.

BTW The 13.0.0-rc01 also works when plugin is applied directly to the app module

Simple fix may be to set apiVersion and languageVersion:

kotlin {
    compilerOptions {
        apiVersion.set(KotlinVersion.KOTLIN_1_8)
        languageVersion.set(KotlinVersion.KOTLIN_1_8)
    }
}

Issue can be reproduced in android-showcase project - just update AboutLibraries version to 13.0.0-rc01 in gradle/libs.versions.toml and run Sync Project With Gradle Files action in Android Studio
