Watching file changes with java.nio.file.WatchEvent does not work on recent MacOS versions

[mkjsix]

When using Graalvm RESTHeart allows for hot reloading of Javascript files in the plugins folder. However this works fine with all OS except for MacOS 15 Sequoia. Tested successfully with Linux, Windows 10 and MacOS 12.

To Reproduce

Steps to reproduce the behavior:

1. build with mvn clean package
2. copy the examples javascript plugins cp -r examples/js-plugin core/target/plugins
3. start RESTHeart with Graalvm java -jar core/target/restheart.jar -s
4. edit one of the javascript files in core/target/plugins/js-plugin
5. Nothing happens, file is not reloaded

Expected behavior

The javascript plugin should be reloaded and related logs must appear

Additional context

Tested with RESTHeart 8.1.1, 8.1.6 and building from master branch commit 1f46adb42.

The file watching mechanism is implemented in class org.restheart.utils.DirectoryWatcher
