Technical summary

cfn-lint cannot find or apply the expected Step Functions StateMachine schema JSON for CloudFormation validation.

Point the schema loader/rule to the correct AWS::StepFunctions::StateMachine schema location and validate Definition fields through that schema.

This issue is schema-location specific, so changing generic resource validation would miss the Step Functions failure.

The snippet uses native project logic; the resolver is called with the CloudFormation resource object that cfn-lint is about to validate. The helper result is consumed directly by the patched code path.

After applying the patch, keep the import smoke test for the affected package:

python3 -c "import cfn_lint; print('smoke test OK')"
