feat: bump kotlin version to 1.9.24

[syall]

Issue #

There were a lot of noisy logs from Gradle / Kotlin, e.g.

java.rmi.ServerError: Error occurred in server thread; nested exception is: 
Could not connect to kotlin daemon. Using fallback strategy.
	java.lang.AssertionError: symbolic reference class is not accessible: class sun.nio.ch.FileChannelImpl, from class org.jetbrains.kotlin.com.intellij.util.io.FileChannelUtil (unnamed module @46805db7)
...

This PR should fix all of the noise (at least locally).

Looks like CI still has noisy log, but at locally they are gone.

My guess is that it could be the gradle version, but unsure.
