[Bug]: Artifacts are placed in directory of lowest `Directory.Build.props` if more than one is present

[Ero]

Issue Description

I import ./Directory.Build.props into ./src/Directory.Build.props. In ./Directory.Build.props, I set ArtifactsOutputPath to $(MSBuildThisFileDirectory)\artifacts. This causes a ./src/artifacts directory to be used for the artifacts of the projects in ./src. I don't want this, I want all artifacts to be placed in ./artifacts.

Steps to Reproduce

1. Create or open any project.
2. Create or open ./Directory.Build.props, add the following to it:

   <Project>
   
     <PropertyGroup>
       <UseArtifactsOutput>true</UseArtifactsOutput>
       <ArtifactsOutputPath>$(MSBuildThisFileDirectory)\artifacts</ArtifactsOutputPath>
     </PropertyGroup>
   
   </Project>

3. Create or open ./src/Directory.Build.props, add the following to it:

   <Project>
   
     <Import Project="$([MSBuild]::GetPathOfFileAbove('$(MSBuildThisFile)', '$(MSBuildThisFileDirectory)\..'))" />
   
   </Project>

4. Build any project in ./src/*.
5. Observe ./src/artifacts being used for the build results.

Expected Behavior

Artifacts are placed in ./artifacts.

Actual Behavior

Artifacts are placed in ./src/artifacts.

It's ArtifactsPath. That's embarrassing.
