This change to the appveyor CI config for msvc builds reverses a change introduced in #19960. It re-applies a setting to inform vcpkg to only build release vesions of the dependencies rather than the default of debug and release.

It had been expected that the vcpkg manifest mechanism introduced in #19960 would do this automatically but it turns out not to be the case.
