根据文件结构生成md文件目录

import * as fs from 'fs';
import * as path from 'path';
const rootDir = '../assets/tutorials'; // 根目录
// const outputFile = '../assets/tutorials/sidebar目录.md'; // 输出到tutorials文件夹
const outputFile = 'sidebar目录.md'; // 输出文件名

//     const filePath = path.join(dir, file);
//     const stats = fs.statSync(filePath);
//   if (stats.isDirectory()) {
//       if (path.extname(file) === '.md') {
//         const relativePath = path.relative(rootDir, filePath);
//         const link = relativePath.replace(/\\/g, '/');
//         result.push(`${'  '.repeat(depth)}- [${path.basename(file, '.md')}](${link})`);
// 递归遍历目录，返回目录结构的数组
/**
 *  ts-node .\exportMdDirectory.ts执行在当前目录下会生成一个sidebar文件

        subDirs.push(`${'  '.repeat(depth)}- **${file}**`);
