Add support for optional authorizations for OpenAPI

[m0uka]

Hey, just checked out your latest OpenAPI update, and it looks great!

One thing is bugging me though:
You don't support optional authorizations - an empty security object entry should signify that the authorization is optional, see OAI/OpenAPI-Specification#14 (comment)

Right now for this schema, authorization is required, but it should be optional:

 /v1/checkouts:
    post:
      tags:
        - checkout
      summary: Create a checkout session
      description: "Creates a checkout session using a Customer token.\nAfter creating the checkout session, redirect the customer to the `url` returned."
      parameters:
        - name: x-paynow-customer-ip
          in: header
          description: The IP address (IPv4 or IPv6) of the customer. Required if the request is not being made from the customer's browser.
          schema:
            type: string
            format: ipv4
        - name: x-paynow-customer-countrycode
          in: header
          description: 'The customer''s country code in ISO 3166-1 alpha-2 format. Optional, but recommended if you have this available.'
          schema:
            pattern: '^[A-Z]{2}$'
            type: string
      requestBody:
        content:
          application/json:
            schema:
              $ref: '#/components/schemas/CreateCheckoutSessionRequestDto'
          text/json:
            schema:
              $ref: '#/components/schemas/CreateCheckoutSessionRequestDto'
          application/*+json:
            schema:
              $ref: '#/components/schemas/CreateCheckoutSessionRequestDto'
      responses:
        '200':
          description: OK
          content:
            application/json:
              schema:
                $ref: '#/components/schemas/CreateCheckoutSessionResponseDto'
        default:
          description: Error response
          content:
            application/json:
              schema:
                $ref: '#/components/schemas/PayNowError'
      security:
        - { }
        - Customer: [ ]

Thanks!
