spaceDelimited option is not working

[jerearaujo03]

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
