locale issues: need different title href URL and home page hero link

[ShenQingchuan]

Problem 1

Describe the bug
I need '/' as the title href for English version, and '/zh/' for Chinese version.
But I didn't found any useful suggestions in the documentation.

To Reproduce
switch to the '/zh/xxx' page, but the title href is still targeting to '/':

Expected behavior
'/zh/xxx' pages' titie href is suppposed to be '/zh/' ( which defines as the key of themeConfigs.locales)

System Info

• vitepress version: v0.10.5
• vite version: v2.0.0-beta2
• Node version: v12.16.2
• OS version: 64bit Mac OS X 10.15.6 19G2021

Problem 2

When I toggle the language, the actionText in docs/index.md and docs/zh/index.md doesn't work well as expected:

seems like the reactivity was lost when deconstructed props....

对问题 2 的解决方案 👆

请 @yyx990803 审阅

导致错误的原因：

1. 从 defineProps() 结构出来的变量 丢失了响应性
2. useNavLink 方法中 props 计算属性的闭包函数缓存了该 item 值
3. 再从

   vitepress/src/client/theme-default/components/NavLink.vue

   Line 19 in a9f7574

   const { props: linkProps, isExternal } = useNavLink(item)

   解构出去时，props 内的所有属性都将永远不变

解决方案：

将传入 useNavLink() 的参数更改为 Ref，保证其响应性

实现效果：
