fix(operation): recognize wildcard HTTP status codes as documented responses

When a response like 4XX is defined in the spec, individual status codes
within that range (e.g. 401, 404) should not be marked as "Undocumented".
The existing check only matched exact status code strings and "default".
This adds a fallback check for range patterns (1XX, 2XX, 3XX, 4XX, 5XX)
per the OpenAPI specification.

Fixes #6175
