Migrate to Kotlin DSL build script to align published Kotlin version with Gradle

[cloudshiftchris]

Currently the build script include the Kotlin JVM distribution, specified @ v 1.7.10, and java-gradle-plugin (to publish as a plugin). This results in published version metadata for Kotlin dependency on v1.7.10, which is incorrect (it must match Gradle Kotlin version).

When using axion 1.14.1 to publish a Gradle plugin (that itself uses Kotlin) an error occurs:

FAILURE: Build failed with an exception.

The idiomatic way to express a Kotlin dependency for a Gradle plugin is to use kotlin-dsl plugin, only available when the build script itself is written in Kotlin Gradle DSL.

This PR migrates the build script to semantically-equivalent Kotlin DSL syntax.
