Remove Kotlin/Jupyter Gradle plugin (#447)

Remove Kotlin Jupyter Gradle plugin in order to avoid its reliance on
dev versions of the Kotlin Gradle plugin (and the Kotlin compiler). The
original motivation for this was one Kotlin/Jupyter version that was
relying on an unpublished KGP version, [failing builds][1] on #424.

/>

That's since been resolved, but beta versions of KGP keep being used and
I'd rather avoid publishing a library built with pre-release versions of
KGP.

/>

The integration that was previously facilitated by the plugin is now
done manually. `examplesTest` guarantees this is functional.
