[BUG] code block对C# Razor/Blazor的渲染有问题

[jeffgyf]

Bug Description
Razor是C# Blazor UI框架使用的混合了html和C#的语法，在chatbox的markdown code block中渲染时会出现错误，C#部分会被重新错误地排版

正确的应该是

@page "/counter"
@using System.ComponentModel.DataAnnotations

<div class="container">
    <h1>helloworld</h1>
</div>

@code {
    private int currentCount = 0;
    private UserModel userModel = new();

    private void IncrementCount()
    {
        currentCount++;
    }

    private void HandleValidSubmit()
    {
        // Handle the valid form submission
        Console.WriteLine($"Form submitted for {userModel.UserName}");
    }

    public class UserModel
    {
        [Required]
        [StringLength(50, MinimumLength = 3)]
        public string UserName { get; set; } = string.Empty;

        [Required]
        [EmailAddress]
        public string Email { get; set; } = string.Empty;
    }
}

希望能按照原有markdown内容来显示，不进行额外的重新排版。

python的代码也有问题，缩进不对
