Merge #523

523: Add code samples and remove useless ones r=curquiza a=curquiza

I created [scripts to manage code samples](https://github.com/meilisearch/integration-automations/pull/164) (internal only)

1. I found out the following code samples are still in this repo but not used by the documentation anymore, so I removed them:

```bash
meilisearch-rust
- 'settings_guide_filterable_attributes_1' not found in documentation
- 'settings_guide_typo_tolerance_1' not found in documentation
- 'documents_guide_add_movie_1' not found in documentation
- 'getting_started_communicating_with_a_protected_instance' not found in documentation
- 'faceted_search_facets_1' not found in documentation
- 'faceted_search_2' not found in documentation
```

2. I found the following code samples were missing:

```bash
meilisearch-rust
- 'search_parameter_guide_facet_stats_1' not found
- 'facet_search_1' not found
- 'facet_search_2' not found
- 'facet_search_3' not found
```
However, only `search_parameter_guide_facet_stats_1`was added because of missing feature implementation for the others
