fix(hr): Ensure that the msbuild version used is properly aligned

Ensures that the MSBuild version is determined using the appropriate folder, where `dotnet --version` used the latest available SDK on the machine. With this change, the MSBuild version will be the one explicitly used by the app. Combined with unoplatform#14170, the devserver now completely uses the appropriate SDK/runtime version based on the app's compilation.
