This is a special treatment to avoid merging anything to Reference Object.
The reference object can have only $ref field.

# invalid 
  schema:
     $ref:  "#/components/schemas/Pet"
     description: "override"

# valid 
  schema:
     allOf:
      - $ref:  "#/components/schemas/Pet"
      - description: "override"

Is this for the case that $ref is manually added to an OpenAPI schema file? If you manually maintain the schema of the response, why don't you skip updating OpenAPI from such test cases? Do you have a test case that calls multiple endpoints and want to update OpenAPI for only one of these?

elsif base[key].is_a?(Array) && value.is_a?(Array)
# parameters need to be merged as if `name` and `in` were the Hash keys.
if key == 'parameters'
base[key] |= value

I wondered if just overwriting the value of base is fine, but given that what we have as an array in the current test in this repository are just servers, tags, parameters, and example, it's probably okay to rewrite it, ignoring the possibility of the need to partially update arrays inside it. We may need to recursively do something if we find other array fields that are not compatible with this idea, but I don't come up with such a thing at this moment.

Similar to https://github.com/k0kubun/rspec-openapi/pull/55/files#r877575816, as long as it updates only fields that rspec-openapi generates, it's probably fine, I guess.
