Suppress or resolve jdk24 native-access warning

[ben-manes]

In jdk24, the upcoming restrictions for native access produces a warning as the default will change in a later version. Since this is produced by Gradle itself, and for a build without its own native platform dependencies, I think it should be resolved by the Gradle team and not by end users. Here is the build scan for this github action build.
