Support K2 about proguard HOT 2 OPEN

@mgroth0 , it seems you are using incorrect gradle kotlin plugin. Try to use 2.0.0-Beta2 (Beta5 now). I see proguard uses version from the dependency.
FYI: it have an error still for Kotlin 2.0.0 metadata, but another one:

Encountered corrupt @kotlin/Metadata for class com/example/Example (version 2.0.0).

from proguard.

Thank you for the update @timeking . I am not sure what you mean about me using the incorrect plugin, at the time I wrote this I was using 2.0.0-Beta2.

So if I understand correctly, you are saying that the "Kotlin versions up to 1.9 are supported." is now fixed, however there is some other issue with K2 now. In that case, I propose we keep this open so we can track when K2 is fully ready.
