[v1.18.0] Add `queryVector` to search responses and support index renaming

Context

We want to update the SDK to support Meilisearch 1.18 features.

Description

When search requests include the retrieveVectors parameters, the API responses will now include a queryVector field. We want to update the SDK methods to return this field accordingly.

Additionally, Meilisearch now supports renaming indexes. There are two ways to achieve this. The examples below both demonstrate how to rename indexA to indexB:

# Using index swapping
curl \
  -X POST 'MEILISEARCH_URL/swap-indexes' \
  -H 'Content-Type: application/json' \
  --data-binary '[
    {
      "indexes": [
        "indexA",
        "indexB"
      ],
      "rename": true
    },
  ]'

# Using index update
curl \
  -X PATCH 'MEILISEARCH_URL/indexes/indexA' \
  -H 'Content-Type: application/json' \
  --data-binary '{ "indexUid": "indexB" }'

Tasks

• Update the search responses to include queryVector when necessary
• Update the index update method to allow renaming
• Update the index swapping method to allow renaming
• Add new test cases to test the implementation
• Add an example under the rename_an_index_1 YAML key in .code-samples.meilisearch.yaml. It should be the equivalent of this CURL example

Locate the SDK methods for search responses, index updates, and index swapping, then inspect their existing tests and request/response types. Update the relevant responses and rename options, add test cases, and add the equivalent example under the rename_an_index_1 key in .code-samples.meilisearch.yaml. Done means queryVector is returned when requested and both documented rename paths are supported and tested.
