Merge #432

432: Update version for the next release (v0.23.0) r=bidoubiwa a=meili-bot

This version introduces features released on Meilisearch v1.1.0 🎉
Check out the changelog of [Meilisearch v1.1.0](https://github.com/meilisearch/meilisearch/releases/tag/v1.1.0) for more information on the changes.

### 🚀 Enhancements

- Add a new optional argument to `add_documents_csv`. This argument allows you to customize the separator character in your `csv` file. (#429) `@brunoocasali.`
- Add `client.multi_search()` method to execute multiple search requests simultaneously with different configurations. (#430) `@brunoocasali`
    Usage example:

    ```ruby
    client.multi_search([
      { index_uid: 'books', q: 'prince' },
      { index_uid: 'movies', q: 'prince' },
    ])
    ```
  ⚠️ The `SearchQuery` was not meant to be used if the regular `$index->search()` requests (yet).
