Use a stable Kotlin version

[adamglin0]

The Kotlin version in use is too high. I’d like to downgrade it to 2.3.0.

The issue I’m running into is that the plugin’s runtime classpath pulls in kotlin-stdlib 2.3.20‑Beta1, while the IDE’s bundled Kotlin runtime is 2.3.0. This mismatch ultimately causes a NoSuchMethodError when Koin starts up, hitting Duration.fromRawValue….

If using a version of Kotlin older than 2.3.20-Beta1 is not possible, then the requirements should be updated to specify that 2.3.20-Beta1+ is required (at the time of writing, it incorrectly reads "Kotlin: 2.3+" is required).

I spent a good chunk of time trying to figure out why I couldn't get the plugin working in my project after following the setup documentation, and am disappointed/frustrated to learn that it's because the documentation is wrong!
