title: Swagger How to enable Filter by tag as case insensitive
body: <p>I am using Swagger-UI implemented through Springfox 2.9.2. </p>
  
  <p>I have enabled "Filter By tag" by setting "filter" as true in UiConfiguration.</p>
  
  <pre><code>@Configuration
  @EnableSwagger2
  @Import({BeanValidatorPluginsConfiguration.class})
  //https://www.baeldung.com/swagger-2-documentation-for-spring-rest-api
  public class SwaggerConfiguration {
      .
      .
      .
  
      @Bean
      public UiConfiguration uiConfig() {
      return UiConfigurationBuilder.builder()
              .defaultModelRendering(ModelRendering.MODEL)
              .defaultModelsExpandDepth(-1)
              .displayRequestDuration(true)
              .displayOperationId(false)
              .filter(true)
              .deepLinking(true).build();
      }
  }
  </code></pre>
  
  <p>But this filter is case sensitive. I need to search without case condition.. </p>
  
  <p>How can i make this Tag Filter case insensitive..? </p>
