Add Kotlin version forward compatibility tests

[qurbonzoda]

The need for the backwards compatibility tests is detailed here: #289

Conaider adding tests for forward compatibility. That is, publish kx-benchmark plugin and runtime with an older Kotlin and use it in a project that uses a newer (minor or major) Kotlin version. This would guarantee that kx-benchmark remain compatible with the newest Kotlin versions.

This would also validate the statement like "ensure you're using Kotlin 2.0.0 or newer" in the README.
