Showkase: doesn't support @Composables with default params

Hopefully this is enough of a stacktrace with beta12:

error: com.airbnb.android.showkase.processor.exceptions.ShowkaseProcessorException: Make sure that the @Composable functions that you annotate with the Preview annotation only have a single parameter that is annotated with @PreviewParameter.

@kenyee The stopgap solution would be to just wrap these methods inside a function that doesn’t accept parameters. Definitely not ideal but unblocks you…

fun ModalGripperPreview() {
    ModalGripper()
}

As I think more about it, I think it should be straightforward to add this functionality (support for functions with default params). Will keep you posted!
