Describe the current behavior When importing kubeflow_v2_dag_runner, the import fails with the error:

ImportError: cannot import name 'version' from 'tfx' (unknown location)

Describe the expected behavior When importing kubeflow_v2_dag_runner, the import should succeed. This works fine when using tfx==1.15.1

Standalone code to reproduce the issue

# When using tfx==1.16.0
from tfx.orchestration.kubeflow.v2 import kubeflow_v2_dag_runner
print(dir(kubeflow_v2_dag_runner))

Other info / logs It seems to be failing to find this file: https://github.com/tensorflow/tfx/blob/r1.16.0/tfx/version.py. It seems it has somehow been missed from the release version installed via pypi?
