It looks like newer version of the gradle plugin org.jetbrains.intellij has a gradle wrapper task already setup. This I think downloads the associated grade? See -> https://github.com/JetBrains/gradle-intellij-plugin/blob/master/build.gradle.kts#L162

So these no longer need to be kept in source control for ease of CI builds (I think).
