// Updates the configuration of an existing state machine alias (https://docs.aws.amazon.com/step-functions/latest/dg/concepts-state-machine-alias.html)
// by modifying its description or routingConfiguration . You must specify at least
// one of the description or routingConfiguration parameters to update a state
// machine alias. UpdateStateMachineAlias is an idempotent API. Step Functions
// bases the idempotency check on the stateMachineAliasArn , description , and
// routingConfiguration parameters. Requests with the same parameters return an
// idempotent response. This operation is eventually consistent. All StartExecution
// requests made within a few seconds use the latest alias configuration.
// Executions started immediately after calling UpdateStateMachineAlias may use
// the previous routing configuration. Related operations:
//   - CreateStateMachineAlias
//   - DescribeStateMachineAlias
//   - ListStateMachineAliases
//   - DeleteStateMachineAlias
