Auto generated examples do not work with exploded array type

This specification:

        - in: query
          name: my_param
          schema:
            type: array
            items:
              type: string
            example:
              - one
              - two
          explode: true
          style: form

correctly yields

under 'Query Parameters'.

However, in the auto-generated examples we get for example (in Python):

query = {
  "my_param": "my_param=one&my_param=two",
}

response = requests.get(url, params=query)

which does not produce a request containing my_param=one&my_param=two as url parameters.

Start by tracing the auto-generated Python example path for OpenAPI query parameters, using the exploded array specification and its generated Query Parameters table as the reproduction case. Compare how the example builds request parameters with the documented repeated-key form; done when the generated Python request produces separate my_param=one and my_param=two query parameters.
