spaceDelimited option is not working

Describe the bug

The query param serialization with spaceDelimited option is not working as expected

Expected behavior

The query param values in the URL should be separated by spaces -> v2/authorize/?enrollment_amr_values=pin liveness

Current behavior

The query param values in the URL are separated by comma (',') ->v2/authorize/?enrollment_amr_values=pin,liveness

Steps to reproduce

1. Define this param for a GET request

- name: enrollment_amr_values
      in: query
      description: Specifies the methods to be used for the authorization
      schema:
        $ref: '#/components/schemas/enrollment_amr_values'
      style: spaceDelimited
      explode: false
      examples:
        Pin:
          value: pin
        Liveness:
          value: liveness
        Pin and Liveness:
          value: pin liveness
      required: false

...

components:
  schemas:
    enrollment_amr_values:
      type: array
      items:
        type: string
        uniqueItems: true
        default: [pin]
        enum:
          - pin
          - liveness

2. Go to the documentation page and select many values for the enrollment_amr_values param

Context

I'm working on an oauth2 provider

No source file or test is named. Start by reproducing the spaceDelimited query parameter case from the issue in the generated documentation, then trace the query-parameter serialization entry point; done means the URL uses a space-separated value such as pin liveness instead of pin,liveness.
