RFR: 8327236: JFileChooser/8194044/FileSystemRootTest.java fails on Windows 11: root drive reported as false

[Tejesh R]

The logic no longer applies to window 11 since getParentDirectory("C:\...\\Documents") return "C:\..\\Desktop". This will require thorough analysis and might call for a product fix. Hence bypassing this test for Windows 11 OS.
