Describe the bug

If the key of AWS::StepFunctions::StateMachine DefinitionSubstitutions is the same as the parameter name or resource ID, an E1029 error occurs.
I do not want to use the Sub function. So, I set the DefinitionSubstitutions map to ResouceId: !Ref ResouceId. Then, E1029 is generated when the key is referenced.

$ cfn-lint ./a.yaml
E1029 Found an embedded parameter "${myParam}" outside of an "Fn::Sub" at Resources/TestStateMachine/Properties/Definition/States/Test/Parameters/Key1
a.yaml:28:15

E1029 Found an embedded parameter "${mySnsTopic}" outside of an "Fn::Sub" at Resources/TestStateMachine/Properties/Definition/States/Test/Parameters/Key2
a.yaml:29:15

Expected behavior

pass lint.
