deleteStateMachineVersion
Deletes a state machine version. After you delete a version, you can't call StartExecution using that version's ARN or use the version with a state machine alias.
Deleting a state machine version won't terminate its in-progress executions.
You can't delete a state machine version currently referenced by one or more aliases. Before you delete a version, you must either delete the aliases or update them to point to another state machine version.
