Produces invalid Python code: `module 'temporalio.workflow' has no attribute 'RetryPolicy'`

[donald-pinckney]

Produced this code:

await workflow.execute_activity(
                charge_payment,
                order,
                start_to_close_timeout=timedelta(seconds=30),
                retry_policy=workflow.RetryPolicy(
                    maximum_attempts=1,  # Don't retry payment failures
                ),
            )

Try to repro with:

make an example workflow which is a multi-step order processing workflow, and which may have business logic level failures at some of the later steps. Do it in Python.
