Type annotations for aiobotocore Step Functions

This package provides type annotations for the `aiobotocore` library's Step Functions (SFN) client. It is part of the `mypy-boto3-builder` project, which automatically generates type stubs for all `aiobotocore` services. The versioning of `types-aiobotocore-stepfunctions` aligns with the corresponding `aiobotocore` version, currently 3.4.0. The project maintains an active release cadence, driven by updates to `aiobotocore` and improvements in the `mypy-boto3-builder` itself, ensuring up-to-date type support.
