What version of Docker.DotNet?:

3.125.14

Steps to reproduce the issue: Dockerfile

FROM debian
WORKDIR /data
COPY --chmod=+x . /data

Code (ConsoleApp calling BuildImageFromDockerfileAsync)

using Docker.DotNet;
using Docker.DotNet.Models;
using System.Text;
using ICSharpCode.SharpZipLib.Tar;

using var client = new DockerClientConfiguration(new Uri("npipe://./pipe/docker_engine"))
    .CreateClient();

await BuildDockerImage(client, ".");

static async Task BuildDockerImage(DockerClient client, string dockerFileDirectory)
{
    // Create an ImageBuildParameters object
    var buildParameters = new ImageBuildParameters
    {
        Dockerfile = "Dockerfile",
        Remove = true, // Remove intermediate containers after a successful build
        Tags = new[] { "yourimagename:tag" }, // Set your image name and tag
        ForceRemove = true, // Always remove intermediate containers, even upon failure
        NoCache = true // Do not use the cache when building the image,
    };

    // Read the dockerfile content
    var dockerFileContent = File.ReadAllText(Path.Combine(dockerFileDirectory, buildParameters.Dockerfile));

    // Create a tarball with the Dockerfile
    var tarball = new FileStream("new.tar", FileMode.Create);
    await using (var tarArchive = new TarOutputStream(tarball))
    {
        var tarEntry = TarEntry.CreateTarEntry("Dockerfile");
        var fileBytes = Encoding.UTF8.GetBytes(dockerFileContent);
        tarEntry.Size = fileBytes.Length;
        tarArchive.PutNextEntry(tarEntry);
        tarArchive.Write(fileBytes, 0, fileBytes.Length);
        tarArchive.CloseEntry();
    }

    tarball = new FileStream("new.tar", FileMode.Open);

    // Build the image
    await using (var responseStream = await client.Images.BuildImageFromDockerfileAsync(tarball, buildParameters))
    {
        // Read the response from the Docker API
        using var reader = new StreamReader(responseStream);
        while (!reader.EndOfStream)
        {
            var line = await reader.ReadLineAsync();
            Console.WriteLine(line);
        }
    }
}

What actually happened?:

{"errorDetail":{"message":"the --chmod option requires BuildKit. Refer to https://docs.docker.com/go/buildkit/ to learn how to build images with BuildKit enabled"},"error":"the --chmod option requires BuildKit. Refer to https://docs.docker.com/go/buildkit/ to learn how to build images with BuildKit enabled"}

What did you expect to happen?: Image is created equivalent to doing docker build on the command line.
