Invalid type for children of nested route when overiding path

[finlayacourt]

Reproduction: https://codesandbox.io/p/github/finlayacourt/unplugin-vue-router-issue/master

Consider,

src/pages/
├── parent/
│   └── child.vue
└── parent.vue

with custom path in parent.vue

<route lang="json">
{
    "path": "/"
}
</route>

The generated type for child.vue is

export interface RouteNamedMap {
  '/parent/child': RouteRecordInfo<
    '/parent/child',
    '/parent/child', // !!!
    Record<never, never>,
    Record<never, never>
  >,
}

but should be

export interface RouteNamedMap {
  '/parent/child': RouteRecordInfo<
    '/parent/child', 
    '/child', // !!!
    Record<never, never>,
    Record<never, never>
  >,
}

Thanks! I have a few other changes pending before releasing but this should hopefully not take too long
