Adding the Gradle plugin to buildSrc triggers warnings

[martinbonnin]

A simple buildSrc/build.gradle.kts file like below:

plugins {
    `embedded-kotlin`
}

repositories {
    mavenCentral()
}


dependencies {
    implementation("org.jetbrains.kotlin:kotlin-gradle-plugin:1.7.0")
    implementation("io.arrow-kt.analysis.kotlin:io.arrow-kt.analysis.kotlin.gradle.plugin:2.0.2") 
}

triggers these warnings:

I believe kotlin-stdlib should be excluded from the dependencies because Gradle will provide its own. I'm not sure about kotlin-script-runtime. Is it something that's used by the Gradle plugin?
