Fix official build break (dotnet#7639)

Regressed with dotnet#7610. The CopyFiles, PublishPipelineArtifact and PublishTestResults steps should only be executed when running in the public team project as internal builds don't run tests. This change just mimics the condition that was already on the "Run Tests" powershell step.
