fix: include sagemaker.mlops subpackages in sagemaker-mlops wheel (Fixes #5612)

Set namespaces=false to ensure subpackages sagemaker.mlops,
sagemaker.mlops.feature_store, and
sagemaker.mlops.feature_store.feature_processor are included in the
wheel distribution. Previously, namespaces=true caused setuptools to
treat sagemaker as a PEP 420 namespace package, excluding all
subdirectories from the wheel.

Fixes #5612
