Describe the bug
vcpkg's msbuild integration (in vcpkg.targets) displays a message Using triplet "x64-windows" from "<vcpkg-root>". Since #4361 this message has importance high (instead of the previous normal) which results in a lot of unnecessary build output. This change seems like a forgotten debugging aid missed in the review.

To Reproduce
Steps to reproduce the behavior:

1. vcpkg install and export any port as nuget.
2. Add the nuget package to a C++ project in Visual Studio.
3. Build with the default MSBuild verbosity (Minimal).

Expected behavior
No message.
