title: OpenAPI (Swagger) not working correctly with array type
body: <p>I using <code>SpringBoot</code> and <code>springdoc-openapi-ui</code>. I have controller with method, which contain array as url param:</p>
  <pre class="lang-java prettyprint-override"><code> @Parameters(value = {
              @Parameter(in = ParameterIn.QUERY, name = &quot;output&quot;, example = &quot;[f1,f2,f3]&quot;,
                      content = @Content(array = @ArraySchema(schema = @Schema(type = &quot;string&quot;))))
  })
  public ResponseEntity&lt;Object&gt; showReportData(@RequestParam(value = &quot;output&quot;) String[] outputFields) {
  //some body
  }
  </code></pre>
  <p>But, when I open <code>SwaggerUI</code>, I can't see my example values in items textbox:
  <a href="https://i.stack.imgur.com/WwUlU.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/WwUlU.png" alt="enter image description here" /></a></p>
  <p>And when I click execute, I see this param in request:
  <a href="https://i.stack.imgur.com/BbPZO.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/BbPZO.png" alt="enter image description here" /></a></p>
  <p>Why is this happening? Why is the example array not displayed in item?</p>
