Subject: [PATCH 2/2] fix: move BaseIntermediateOutputPath to
 Directory.Build.props to fix MSB3539 warning

The MSB3539 warning occurs because BaseIntermediateOutputPath and
BaseOutputPath were being set in DocoptNet.csproj, which is too late
in the MSBuild evaluation order. These properties must be set before
Microsoft.Common.props is imported. Directory.Build.props is the
correct location since it's imported early enough.
