[v1.16.0] Add support for multi-modal search

This issue follows the mega issue of changes related to v1.16.

Description

We want to update this SDK to allow using indexing and search fragments to enable multi-modal search. This feature is introduced in Meilisearch 1.16.

For more information, see the embedder settings API.

NB: As of Meilisearch 1.16, this feature is experimental. This might require updating the API related to experimental features.

Tasks

• [ ] Update settings methods to allow configuring indexingFraments and searchFragments
• [ ] Add new tests cases
• [ ] Add code sample in .code-samples.meilisearch.yaml under the search_parameter_reference_media_1 key. The example should be similar to this CURL example
