[Matthias Baesken]

Hello, please review this small change.
The OS detection code of the JDK/JVM should recognize the new Windows server 2022 :

https://docs.microsoft.com/en-us/lifecycle/products/windows-server-2022
https://docs.microsoft.com/en-us/windows-server/get-started/windows-server-release-info

The build number of Windows server 2022 according to the documentation in the second link is 20348 .
Thanks, Matthias
