Typo in Step Object description

Clarified this in the Slack channel:

Under https://spec.openapis.org/arazzo/latest.html#step-object

Describes a single workflow step which MAY be a call to an API operation (OpenAPI Operation Object or another Workflow Object).

Seems to have a misplaced parenthesis. I believe this:

Describes a single workflow step which MAY be a call to an API operation (OpenAPI Operation Object) or another Workflow Object.

Would make it clearer that a workflow step is EITHER an API operation or another Workflow
