Deep nested side bar title isn't indented.

[soumi-akira]

Describe the bug

When side bar has more than 4 depth nested title, indent is broken.

Reproduction

.vitepress/config.ts

import { defineConfig, DefaultTheme } from "vitepress";

export default defineConfig({
  title: "Some document",
  description: "Just playing around.",
  themeConfig: {
    sidebar: {
      "/": [
        {
          text: "1",
          children: [
            {
              text: "2",
              children: [
                {
                  text: "3",
                  children: [
                    {
                      text: "4",
                      children: [
                        {
                          text: "5",
                          children: [
                            {
                              text: "6",
                              children: [],
                            },
                          ],
                        },
                      ],
                    },
                  ],
                },
              ],
            },
          ],
        },
      ],
    },
  },
});

this produce side bar like bellow.

Expected behavior

Produce correct indent.

The image above is made by changing sub title padding to 0.3rem 1.5rem 0.3rem 5rem for 5 and 0.3rem 1.5rem 0.3rem 6rem for 6 with Chrome dev tool.

Additional context

I know if we use deep nested sub title, the layout is broken in many case, but at least it should be able to choice whether we use it or not I think.
Even if it's not supported officially, if we get it work by adding some script or something, it's welcome😀

Thanks for the feedback! But closing it due to sidebar has no more nested structure in theme-next 🙇‍♂️

[adam-tylr]

Is a nested sidebar intentionally not supported or is it something that could be implemented in the future?

@adam-tylr It's already implemented (#851) though we haven't documented it yet.
