Duplicate Meta Descriptions In Build Output

[harlan-zw]

Describe the bug

When you set a custom meta description within the config.js and set a description at a page level using frontmatter, the build output has 2 meta descriptions

To Reproduce

Add a description in the vitepress config

// .vitepress/config.js

module.exports = {
  // ...
  description: 'Hey 👋 I'm building Laravel & Vue projects and would like to share my journey with you.',
  // ...
}

Add a description for a page

// about/index.md

---
title: About
description: "My name's Harlan. I am a full stack developer living and working out of Sydney, Australia."
head:
- - meta
  - name: description
    content: "My name's Harlan. I am a full stack developer living and working out of Sydney, Australia."
---

# {{ $page.title }}

Hey! Thank you for checking out my site 😊

Live example: https://harlanzw.com/about/

Expected behavior

A single meta description should be present, with the description from the page (about.md) taking precedence over the vitepress config description.

System Info
