a path named /zh-CN/changes.html will generate out a file named /zh-CN/changes.html.html
``` js
routes.push({
  path: '/zh-CN/changes.html',
  component: () => import('../zh-CN/changes.md')
})
```

I want to use extension `.html` for every page, so I add a route named `/zh-CN/changes.html`. It works fine in dev mode but then I get a  `/zh-CN/changes.html.html` after `ream generate`.

Any workaround for this situation? or I will have to write a script for rewriting names :sweat_smile:
