Update Kotlin version to 1.9.23

[buenaflor]

There is a known issue with compiling on xcode 15.3 that is fixed only on Kotlin 1.9.23 and higher.

We are on 1.9.21 and I have to change it to 1.9.23 every time when developing on KMP.

See: https://youtrack.jetbrains.com/issue/KT-65542/Cinterop-tasks-fails-if-Xcode-15.3-is-used

I'm not sure about the backwards compatibility implications but I think it's fine?

I think this change is generally necessary since the default xcode version on github is now 15.4

I think it's fine, just a patch version
