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

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.

Or 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 each of the 4 languages, in a directory for each

No file or test is named. Start by reproducing the Python multi-step order-processing workflow described in the issue and inspect where the generated retry policy is sourced. Done means the generated example uses an available API and no longer produces the reported AttributeError.
