**Description** Batch deletion from index expects an array of int for document ID even though said ID can be any valid String, such as a UUID for example. **Expected behavior** Batch deletion should work similar to single deletion - it should accept strings of any kind. **Environment (please complete the following information):** - OS: Ubuntu 22.04 - Meilisearch version: 0.28 - meilisearch-swift version: 0.14.1
