Subject: [PATCH] [CI] Fix mac tests on  post build pipeline (#20543)

To be able to download a artifact from a build that triggered the post
build pipeline we cannot use the DownloadPipelineArtifact task with the
same values since the artifact wont be found. This change adds an if
statement to do the right thing based on the trigger so that we can have
both pipelines running correctly until we remove the tests from the
build.
