Easy way to create landing page

[pi0]

Is your feature request related to a problem? Please describe.

While it is possible to create pages/index.vue to design a custom landing page (#94), i found it too complex to implement for vite docs having an elegant and simple landing. We can provide a more convenient way to make it by introducing landing/home layout.

Describe the solution you'd like

Similar to vuepress/vitepress, we might special layout for home/landing:

Example: (src)

---
home: true
sidebar: false
heroImage: /logo.svg

actionText: Get Started
actionLink: /guide/installation

footer: MIT Licensed | Copyright © 2014-present Evan You, Guillaume Chau
---

Renders into https://devtools.vuejs.org/

Describe alternatives you've considered

pages/index.vue with provided components but i think it is still overkill and not markdown centric

Additional context

It's planned, thanks for creating the task :)

Once we have the final landing page for Docus that @bdrtsky is working on, we will be able to refactor and see the best way to convert it to Markdown file.
