Downgrade kotlin plugin version to 1.9.0

Earlier upgrade in 276e0655f4 was too high, since Android Studio Iguana is still bundled with Kotlin plugin with version `232-1.9.0-release-358-AS10227`. The result of the mismatched plugin is a build failure like:

`Module was compiled with an incompatible version of Kotlin. The binary version of its metadata is 1.9.0, expected version is XXX`

Although according to https://plugins.jetbrains.com/plugin/6954-kotlin, the 1.9.23 is already available. So we will be able to upgrade again soon.

Version 1.9.0 is still good enough for the compose compiler to be 1.5.0+ according to https://developer.android.com/jetpack/androidx/releases/compose-kotlin#pre-release_kotlin_compatibility
