设置base后页面跳转404

[cmtlyt]

Describe the bug

1. 页面跳转404
2. themeConfig.sidebar.items.link 需要手动添加 base路径才能正常跳转

Reproduction

// .island/config.ts

export default defineConfig({
  // ...
  base: '/test/',
  // ...
})

// docs/index.md
---
hero:
  // ...
    actions:
      - theme: brand
        text: go
        link: /article
  // ...
---

Expected behavior

期望跳转到/program-guide/article

实际跳转到/program-guide/program-guide/article

如果配置actions link为/program-guide/article

则会跳转到/program-guide/program-guide/program-guide/article

如果同时设置了locales和base的话,base会被强制转置到locales

我直接使用master分支添加base配置后发现的
