[v1.8] Support searchCutoffMs setting

[curquiza]

Following this central issue

This is related to a newly introduced feature in Meilisearch v1.8.0: the searchCutoffMs setting.

Refer to docs for more information.

• Add the new settings: searchCutoffMs with get, update, and reset methods associated.
  Here are the JS equivalents in meilisearch-js you should create for this repository:

client.index('indexName').getSearchCutoffMs(); // calls GET /indexes/:uid/settings/search-cutoff-ms
client.index('indexName').updateSearchCutoffMs(150);  // calls PUT /indexes/:uid/settings/search-cutoff-ms
client.index('indexName').resetSearchCutoffMs(); // calls DELETE /indexes/:uid/settings/search-cutoff-ms

• The methods associated with the /settings API route (to get, reset and update the settings globally) must be able to receive in the payload the new searchCutoffMs field
• ⚠️ Add integration tests ⚠️
• Update the .code-samples.meilisearch.yaml
  • Add get_search_cutoff_1 key and “translate” the following curl example by using the newly added methods: https://github.com/meilisearch/documentation/blob/84fad8b88a9b50a6e79bccb7da159bcf78193e54/.code-samples.meilisearch.yaml#L1191
  • Add update_search_cutoff_1 key and “translate” the following curl example by using the newly added methods: https://github.com/meilisearch/documentation/blob/84fad8b88a9b50a6e79bccb7da159bcf78193e54/.code-samples.meilisearch.yaml#L1194
  • Add reset_search_cutoff_1 key and “translate” the following curl example by using the newly added methods: https://github.com/meilisearch/documentation/blob/84fad8b88a9b50a6e79bccb7da159bcf78193e54/.code-samples.meilisearch.yaml#L1199
