Description of changes:
Hi😀 Thanks for the useful patterns!

To keep this pattern maintainable, I updated the aws-cdk-lib.

Check

cdk deploy completed successfully and works good.

$ aws stepfunctions start-execution  --name "test" --state-machine-arn "arn:aws:states:ap-northeast-1:000000000000:stateMachine:SQSWorkflowStateMachineD7FFB1AA-Zuxb7GWU1X97" --input "{\"message\": {\"hello\" : \"world\" } }"
{
    "executionArn": "arn:aws:states:ap-northeast-1:000000000000:execution:SQSWorkflowStateMachineD7FFB1AA-Zuxb7GWU1X97:test",
    "startDate": "2026-05-26T09:42:16.817000+09:00"
}

Thank you😀
