./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

This Android Gradle plugin (7.1.3) was tested up to compileSdk = 32

This warning can be suppressed by adding

to this project's gradle.properties

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)

https://github.com/JetBrains/compose-multiplatform/commit/cbdb0eb69364ff71e28fb75b781d751d76219c2b

Adding the coroutines dependency in commonMain helps.

Thanks!

Fixed :)
