Hotfix for kt version warning in Compose projects

Compose projects must currently use Kotlin 1.5.10, but Android Studio
bundles Kotlin IDE plugin 1.5.20, and so the IDE warns that the IDE
version does not match the compiler version. This change suppresses
that warning.

The warning is only suppressed in projects which used Compose.
