Add a ViewModel to Dessert Clicker: Android Basics in Compose

[otaviocardoso]

Step 3 shows configuration of build.gradle files in project and app directories, but the actual project uses build.gradle.kts files, written in another DSL.

Thanks to this stackoverflow question I could make it work like this:

buildscript {
   extra.apply {
       set("lifecycleVersion", "2.5.1")
   }
}

dependencies {
    val lifecycleVersion by rootProject.extra
    // ...
    implementation("androidx.lifecycle:lifecycle-viewmodel-compose:$lifecycleVersion")
}
