Remove PET artifact download from DevDiv release pipelines (#1839)

Remove the Monaco-scoped PET artifact download from the new DevDiv
pre-release and stable pipelines.

This removes the failing DownloadPipelineArtifact step, its PET
directory and target setup, and the now-unused stable petBranch
parameter. When the extension does not bundle PET, it falls back to the
Python extension's PET binary.
