侧边栏配置支持多侧边栏配置,希望导航栏也支持下

export default {
  themeConfig: {
    sidebar: {
      // 当用户位于 `guide` 目录时，会显示此侧边栏
      '/guide/': [
        {
          text: 'Guide',
          items: [
            { text: 'Index', link: '/guide/' },
            { text: 'One', link: '/guide/one' },
            { text: 'Two', link: '/guide/two' }
          ]
        }
      ],

      // 当用户位于 `config` 目录时，会显示此侧边栏
      '/config/': [
        {
          text: 'Config',
          items: [
            { text: 'Index', link: '/config/' },
            { text: 'Three', link: '/config/three' },
