[Android] Update Java/AGP/Gradle warning compatible Java range (#135710)

Specifies that compatible Java range stated in warning when Java version is incompatible with our template AGP & Gradle versions notes an exclusive upper bound Java version. This was a bug from https://github.com/flutter/flutter/pull/131444, and I will file a CP request to stable once this lands.

The warning uses [`getJavaVersionFor`](https://github.com/flutter/flutter/blob/b5c8fd11e4906d900039584b4f67c9753327060c/packages/flutter_tools/lib/src/android/gradle_utils.dart#L606), which returns an exclusive upper bound, which is why this fix is necessary.
