[Python] generated docstrings for 'google.cloud.container_v1.types.Cluster' break docs build

The actual file containing that docstring is google/cloud/container_v1/proto/cluster_service_pb2.py. The offending bit is:

      current_node_version:
          [Output only] Deprecated, use `NodePool.version </kubernetes-e
          ngine/docs/reference/rest/v1/projects.zones.clusters.nodePool>
          `__ instead. The current version of the node software
          components. If they are currently at multiple versions because
          they're in the process of being upgraded, this reflects the
          minimum version of all nodes.

where the backtick-double-underscore is wrapped away from the closing angle bracket.

@tseaver How much of a blocker is this for the Yoshi team? We can bump this to a P1 if it's introducing a lot of toil on your end.

Thanks, but /google-cloud-python/pull/6634/ adds a workaround for it in container/synth.py, so we aren't blocked.

@lukesneeringer Could you provide an update? (We're about to pass the SLO window on this one)

[noahdietz]

Is this related to a line wrapping bug #2159 ?

[vchudnov-g]

@lukesneeringer @hzyi-google Any updates on this? We're out of SLO.

FWIW, the workaround added in googleapis/google-cloud-python#6634 is still in effect when generating google-cloud-container:

synthtool > Replaced 'nodePool>\\n' in google/cloud/container_v1/proto/cluster_service_pb2.py.
synthtool > Replaced '(\\s+)`__ instead' in google/cloud/container_v1/proto/cluster_service_pb2.py.
