Subject: [PATCH] build/windows, devel-docs: The minimum Windows version is
 actually 10.0.18362.0

DWMWA_USE_IMMERSIVE_DARK_MODE and activeCodePage were introduced on "1903"
The Store version manifest was already using this as minimum version since
day 1, so the commit just extends that minimum version to the Installer.

While is unlikely that users will be affected, we can revert this commit if:
1) LTSC/LTSB users report on tracker that is not possible to install GIMP;
2) we confirm that GIMP works on this machine even with that incompatible API.
