Fix TestErrorJSONOutput test

[ilya-zuyev]

This PR fixes TestErrorJSONOutput integration test
The problem was that after #10452 the error message about incorrect minikube driver changed from The driver ${driver} is not supported on ${os} to The driver ${driver} is not supported on ${os}/${arch}

Before:
