fix ambiguous wording for required win version

[jantari]

Previously this part of the docs stated that Windows version 22H2 was required, but as I learned that is actually wrong:

https://github.com/microsoft/WSL/issues/10853

it is specifically Windows 11 version 22H2 that is required. Windows 10 version 22H2 does not work unfortunately.
