showExtension option on array of strings does not show extensions

[knthls]

Describe the bug
In an openapi spec, using the x-extensible-enum extension and the showAnnotations option, the extension is not rendered, when the type is an array of enum

Expected behavior
I expect the extensions to be shown, similar to what happens when an array of enum is rendered.

Minimal reproducible OpenAPI snippet(if possible)
Consider the following spec:

openapi: 3.1.0
info:
  title: Minimal Museum API
  version: 1.0.0
servers:
  - url: 'https://api.fake-museum-example.com/v1'
paths:
  /museum-hours:
    get:
      summary: Get museum hours
      operationId: getMuseumHours
      responses:
        '200':
          description: Success
          content:
            application/json:
              schema:
                type: object
                properties:
                  hours:
                    type: array
                    items:
                      type: string
                      x-extensible-enum:
                        - OPEN
                        - CLOSED
                  hours2:
                    type: array
                    items:
                      type: string
                      enum:
                        - OPEN
                        - CLOSED

Additional context

I know that x-extensible-enum is not supported directly, however I found that with the showExtensions option enabled, it works well enough for our use case. I do have a fix in mind, however I don't know if this would have any unwanted side effects that I can't think of. I will open a draft PR containing my fix and I would be happy if you would consider my change.
