./gradle build for ImageViewer example fails

[StefanOltmann]

Running ./gradlew build on the current master (commit cbdb0eb) fails due do an issue with the coroutine dependency.

Building https://github.com/JetBrains/compose-multiplatform-template the same way works.

sol@MBP-von-Stefan imageviewer % ./gradlew build            
WARNING:We recommend using a newer Android Gradle plugin to use compileSdk = 33

The build will continue, but you are strongly encouraged to update your project to
use a newer Android Gradle Plugin that has been tested with compileSdk = 33

@dima-avdeev-jb It seems this issue is caused by setting the newer coroutines version only for iosMain (other targets transitively depend on coroutines 1.6.4 used in compose)

cbdb0eb

Adding the coroutines dependency in commonMain helps.

Thanks!

[eymar]

Fixed :)
