Poem

🐰 The playground once stood tall and bright,
With maps and searches in the night,
But now we point to demos fair,
External paths float through the air! ✨

750-750: Consolidate the duplicate geosearch demo reference.

The identical geosearch demo link appears twice in the Geo Search documentation section (lines 750 and 779). Consolidating this to a single reference would improve documentation clarity without sacrificing context. For example, retaining it only at line 779 (after the Requirements section) would place it immediately before the Usage example where readers are most likely to need it.

Apply this diff to remove the redundant reference:

- ✅ cssClasses: The CSS classes to override.
-
-Check out our [geosearch demo](https://github.com/meilisearch/demos/tree/main/src/geo-javascript) for a working example.
-
 #### Requirements

This retains the reference where it appears after the complete Requirements section, which is a more natural flow before the Usage examples.

Also applies to: 779-779
