CamelCase NamingStrategy for enums not working with System.Text.Json

CamelCase NamingStrategy for enums not working with System.Text.Json
NSwag version: 13.15.7

To reproduce:

using System.Text.Json;
using System.Text.Json.Serialization;
using Microsoft.AspNetCore.Mvc;
using NswagApi;

var builder = WebApplication.CreateBuilder(args);
builder.Services.AddEndpointsApiExplorer()
    .AddOpenApiDocument(settings => settings.Title = "Title")
    .Configure<JsonOptions>(options =>
    {
        options.JsonSerializerOptions.Converters.Add(new JsonStringEnumConverter(JsonNamingPolicy.CamelCase));
    });

var app = builder.Build();

app.MapGet("/", () => new SampleDto
{
    Enum = SampleEnum.Foo
});
app.UseOpenApi();

app.Run();

Generated json:

"SampleEnum": {
        "type": "string",
        "description": "",
        "x-enumNames": [
          "Foo",
          "Bar"
        ],
        "enum": [
          "Foo",
          "Bar"
        ]
      }

Looks like it's somehow related to this code in SystemTextJsonUtilities.cs:

public static JsonSerializerSettings ConvertJsonOptionsToNewtonsoftSettings(dynamic serializerOptions)
        {
            var settings = new JsonSerializerSettings
            {
                ContractResolver = new SystemTextJsonContractResolver(serializerOptions)
            };

            if (((IEnumerable)serializerOptions.Converters).OfType<object>().Any(c =>
                c.GetType().IsAssignableToTypeName("System.Text.Json.Serialization.JsonStringEnumConverter", TypeNameStyle.FullName)))
            {
                settings.Converters.Add(new StringEnumConverter());
            }

            return settings;
        }

It simply creates StringEnumConverter without naming strategy.
