Incompatible kotlinx.coroutines dependency is used with Kotlin 1.3+ in Gradle

Reports kotlinx.coroutines library dependencies in Gradle that should be updated to be compatible with Kotlin 1.3+.

Example:

  dependencies {
      implementation 'org.jetbrains.kotlinx:kotlinx-coroutines-core:0.0.1'
  }

The quick fix changes the kotlinx.coroutines library version to a compatible with Kotlin 1.3:

  dependencies {
      implementation 'org.jetbrains.kotlinx:kotlinx-coroutines-core:0.27.0-eap13'
  }
