text: Title: Example for list response is either a list containing only the first element or a list inside a list in redoc
  Body: **Describe the bug**
  When I specify a list as an example (in a raw schema) in redoc only the first item in the given list is displayed as the only item in the example.
  If I wrap the example list into a list, the example is displayed as a list of list.
  
  In swagger I always get a single element list with garbled data.
  
  **To Reproduce**
  Note that this endpoint returns a list of (subset of) icinga (nagios) check items which are converted into the format expected by icinga checks. The data is provided by code that runs these checks and returns the appropriate status code and description.
  
  So this is my application code (I elided some earlier definitions, but you get the idea, I think):
  ~~~python
  STATUS_INFO_NAME_SCHEMA = dict(
      type='string',
      pattern=r'sis\.[a-z_]+',
      description='Name des Checks (beginnt immer mit `"sis."`)'
  )
  
  STATUS_INFO_VALUE_SCHEMA = dict(
      type='string',
      enum=('ok', 'warning', 'error', 'critical'),
      description='Wert oder Schwere ("Severity") des Status.'
  )
  
  STATUS_INFO_TYPE_SCHEMA = dict(
      type='string',
      enum=('direct',),
      description='Nagios/Icinga Typ (immer `"direct"`)'
  )
  
  STATUS_INFO_DESCRIPTION_SCHEMA = dict(
      type='string',
      description='Menschenlesbare Beschreibung des Resultats'
  )
  
  INFO_NAMES = [
      'info',
      'configuration',
      'database',
      'fingerprints',
      'mail_host',
      'django_compatibility',
      'request_stats'
  ]
  
  INFO_NAME_SCHEMA = dict(
      type='string',
      enum=tuple(
          f'sis.{name}'
          for name
          in INFO_NAMES),
      description='Name des Checks (beginnt immer mit `"sis."`)'
  )
  
  INFO_NAGIOS_SCHEMA = dict(
      type='string',
      pattern=(
          f'({" | ".join(INFO_NAME_SCHEMA["enum"])})'
          f' ({" | ".join(STATUS_INFO_TYPE_SCHEMA["enum"])})'
          f' ({" | ".join(STATUS_INFO_VALUE_SCHEMA["enum"])})'
          r' - .+'),
      description='Vollständige Ausgabe des Nagios/Icinga-Checks'
  )

  In swagger, the example looks garbled and only has the first item:
  ~~~json
  [
    {
      "name": "sis.info",
      "value": "ok",
      "type": "direct",
      "description": "string",
      "nagios": " sisVrequest_stats direct  critical - I{P{2prRCQe68zEfoE,tD"
    }
  ]
  ~~~
  
  If I change the raw schema to 
  
  ~~~python
  INFO_ITEM_SCHEMA = dict(
      type='object',
      properties=OrderedDict({
          'name': INFO_NAME_SCHEMA,
          'value': STATUS_INFO_VALUE_SCHEMA,
          'type': STATUS_INFO_TYPE_SCHEMA,
          'description': STATUS_INFO_DESCRIPTION_SCHEMA,
          'nagios': INFO_NAGIOS_SCHEMA,
      }),
      examples=INFO_EXAMPLE)
  ~~~
  
  The example in redoc changes to:
  
  ~~~json
  [
    {
      "name": "sis.info",
      "value": "ok",
      "type": "direct",
      "description": "SIS version devel",
      "nagios": "sis.info direct ok - SIS version devel"
    }
  ]
  ~~~
  
  i.e. just the first item. And swagger displays:
  
  ~~~json
  [
    {
      "name": "sis.info",
      "value": "ok",
      "type": "direct",
      "description": "string",
      "nagios": " sisdfingerprints  direct ok  -  >[U7/ Nw?D+jZQ%=og65=v^v>!Z+^!r)(WY/O46iRA0_4=H"
    }
  ]

  **Expected behavior**
  I expect to be able to give a full **list** as an example to a list response and see exactly that list as an example.
  
  
  I've seen https://drf-spectacular.readthedocs.io/en/stable/faq.html#my-viewset-list-does-not-return-a-list-but-a-single-object as well as https://github.com/tfranzel/drf-spectacular/issues/990 and I've tried to come up with a way to apply the hints in https://drf-spectacular.readthedocs.io/en/stable/faq.html#how-do-i-wrap-my-responses-my-endpoints-are-wrapped-in-a-generic-envelope to an on-the-fly serializer via https://drf-spectacular.readthedocs.io/en/stable/drf_spectacular.html#drf_spectacular.utils.inline_serializer but it seems easier to write a serializer for the data returned by `check.info()`.
  
  That seems wasteful since it already does return an array and I feel it should not be that hard.
  
  Also why does **something** (redoc?) apparently wrap the first element of a list into a list if it's not a list **AND** keep a nested list as is? That garbled swagger output is also very weird.
