Subject: [PATCH] [ML] Fix missing import os in PR pipeline generator

pipeline.json.py uses os.environ.get() inside the ci:run-qa-tests code path
but was missing 'import os'. Any PR carrying the ci:run-qa-tests label
triggered a NameError that crashed the pipeline generator in ~25s, blocking
the entire Buildkite build before any step ran.
