valueFrom does not seem to have a field named workflowStepRef. Was there an example you borrowed the syntax from?

An equivalent way of retrieving that value would be to use an expression. Following this example, you could do:

# ...
        arguments:
          parameters:
          - name: output-value
            value: "{{steps.step-a.outputs.parameters.output-parameter-example-step-a}}"
