title: Enum name generation nswag and swashbuckle
body: <p>I have a Web API that uses <code>swashbuckle</code> to generate swagger ui and json to code generation.The problem is that when I generate the code with <code>nswag studio</code> it doesn't generate enums in proper format. let me explain more clearly. My enum that is created like this in back end:</p>
  
  <pre><code>public enum OrderType
  {
      ASC = 0,
      DESC = 1,
      None = 2,
  }
  </code></pre>
  
  <p>but the result that i get with <code>nswag studio</code> code generator is like this:</p>
  
  <pre><code>[System.CodeDom.Compiler.GeneratedCode("NJsonSchema", "10.1.11.0 (Newtonsoft.Json v12.0.0.0)")]
  public enum OrderInfoOrderType
  {
      [System.Runtime.Serialization.EnumMember(Value = @"None")]
      None = 0,
  
      [System.Runtime.Serialization.EnumMember(Value = @"ASC")]
      ASC = 1,
  
      [System.Runtime.Serialization.EnumMember(Value = @"DESC")]
      DESC = 2,
  
  }
  </code></pre>
  
  <p>my start up code is like this:</p>
  
  <pre><code>services.AddMvc(option =&gt; option.EnableEndpointRouting = false).AddJsonOptions(options =&gt;
          {
              options.JsonSerializerOptions.Converters.Add(new JsonStringEnumConverter());
              options.JsonSerializerOptions.IgnoreNullValues = true;
          });
  </code></pre>
  
  <p>What have I done wrong here?. I'm using <code>.net core 3.1</code>.</p>
