replace URL path for inlined SearchMarkers - fixes #1154

The search index looks like:

```ts
[
 {
   id: 'foo', label: 'security',
   path: '/settings/security', inlining: ['2fa'],
 },
 {
   id: '2fa',
   label: 'two-factor auth',
   path: '/settings/2fa', // guessed wrong by the index generation
 },
 {
   id: 'aaaa',
   parentId: '2fa',
   label: 'totp',
 },
 …
]
```

This file post-processes that index and re-parents the inlined
sections. Problem was, it left the (wrong) `path` untouched.

Replacing the `path` makes the search work fine.
