Rule in OpenApiResponsesRules is too restrictive.

[PerthCharern]

Spec (both V2 and V3):

The Responses Object MUST contain at least one response code, and it SHOULD be the response for a successful operation call.

Our rule:

Responses must contain success response

What I think we should do:

Just check that there is one response. We don't have the capability for the SHOULD type of rule right now.

And there we have justification for creating the notion of a Warning when doing validation :-)
