RFR: 8340387: Update OS detection code to recognize Windows Server 2025

[Matthias Baesken]

Windows Server 2025 will be releases in a few months.
The OS detection code of the JVM/JDK should recognize the new Windows server 2025 version.
(currently Windows server 2022 is printed , that is wrong)

The build numbers of some recent previews documented here
https://learn.microsoft.com/en-us/windows-server/get-started/whats-new-windows-server-2025
are 26080 and 26085 (final release version will most likely be a bit higher).
