Kotlin: Support Kotlin 2.3.0-Beta2

[andersfugmann]

This PR add support for Kotlin 2.3.0-Beta2.

To support Kotlin 2.3.0-Beta2, and update of the rules_kotlin bazel package needs to be updated to 2.2.0. Unfortunatly that drops support for Kotlin 1.6.x and 1.7.x.

If we're removing support for 1.6 and 1.7, then we should move (into v_1_8_0) or delete all the files in utils/versions/v_1_{6,7}*

BTW Kotlin 2.3.0 is released, so you can update 2.3.0-Beta2 to 2.3.0
