Issue:
Support Pattern Response Status Codes (2XX, 3XX, 4XX, and 5XX)
According to Open Api Specification 3.0.0 and above 
the Response Object alows to describe Error Responses in 
https://spec.openapis.org/oas/v3.0.0.html#patterned-fields-0

but the validation currently fails for schemas describing Status ranges.

        


Pull request description:
