    [v3-4-test] Run the lang-SDK conformance serializer in its own virtualenv 
(#75085) (#75111)
    
    The Python side of the SDK serialization conformance checks ran in the
    workspace .venv. prek runs the chart's kubeconform hook at the same time,
    and it syncs that .venv to the kubernetes-tests packages through
    `breeze k8s setup-env`. When the cncf.kubernetes provider landed there
    after the serializer's Python had started, provider discovery found the
    provider's entry point but not its sources on sys.path, and the check
    failed with "No module named 'airflow.providers.cncf'".
    
    Point uv at a dedicated .build/lang-sdk-serialization-venv instead.
    (cherry picked from commit d2a8457e768e1d4ac5b1dd52ba330945c0174d0d)
