    CI builds: disable VSTO manifest and assembly signing so that
    ResolveKeySource (Microsoft.Common.targets) does not attempt to
    locate a certificate that only exists on the developer machine.
    These top-level PropertyGroups are evaluated after the .csproj
    static PropertyGroups, effectively overriding SignManifests and
    SignAssembly for CI.
