Fix documentation of minor versions

[ferki]

This PR fixes the documentation for minor versions of Windows 8.1 and 2012 R2. The docs say it's 2, but tests, code, and other resources indicate it's 3.

Please double check if it's correct, and let me know if I should modify this PR.

Thank you for your PR. You are correct, but it is slightly more complicated; the version returned depends on the version support declared in the manifest: https://docs.microsoft.com/en-us/windows/win32/sysinfo/targeting-your-application-at-windows-8-1

Support for Windows 8.1 (and 10) has been declared in Perl/perl5@9964c51. Could you do some digging to determine which Perl versions have the updated manifest, and then add a footnote that explains that Windows 8.1 and 10 will return version 6.2 on earlier Perl releases? Something like https://docs.microsoft.com/en-us/windows/win32/sysinfo/operating-system-version

Thank you!

which Perl versions have the updated manifest

I did a quick check, and it looks like this change is in v5.24.0 and later, but please verify! (Well, v5.23.3, but the docs probably should not care about beta versions).

Interesting detail, thanks for pointing me to the right docs, I learned something new!

That's my own results too. I'll update this PR with the extra pointers.
