Recognize build 22000 as Windows 11 (#12627)
* winVersion: recognize build 22000 as Windows 11 (21H2). Re #12626.
Despite the name, Windows 11 is powered by Windows 10 technologies internally (therefore major.minor is 10.0). The Windows 11 branding first appeared in build 22000 for Windows Insiders, therefore recognize 'Windows 10' build 22000 as Windows 11 (both the constant and release name were added).
* winVersion: set release name to 'Windows 11' if Windows 11 is indeed in use. Re #12626.
Construct a minimum winVersion.WinVersion class (major, minor, build) and compare it against Windows 11 information. If running Windows 11 (build 22000) or later, set release name to 'Windows 11', otherwise 'Windows 10'.
