[Meilisearch v1.47.0] Add personalized search (experimental)

Context

Meilisearch 1.47.0 adds full support for personalized search (experimental) to the search endpoint.

NB: before 1.47.0, federated search requests did not support personalized search.

Objective

Update the SDK to support personalized search on the search endpoint.

Update the corresponding SDK methods

• Search (POST)
• Search (GET)

Both related API endpoints now accept a new personalize object parameter:

{
  // other request parameters...
  "personalize": {
    "userContext": "The user prefers ..."
  }
}

Tasks

• Add/update methods to handle interacting with the search API endpoints
• Add/update test cases for the new/updated methods
• No code samples to update

Locate the SDK methods corresponding to the Search (POST) and Search (GET) endpoints, then read their existing request handling and related test cases. Add support for the personalize object with userContext, update both endpoint methods, and verify the new behavior with tests for each method.
