Build: Update kotlin to 1.9.22

This update isn't that necessary, but should be considered anyway as it
will do the following:
- Align this library, to that Kotlin version, which is already used by
most of this library's clients and libraries.
- Unblock the usage of the dependency analysis Gradle plugin for this
project.
- Prepares this project for the Kotlin 2+ major update.
