Merge #667

667: Make index swap test more permissive r=curquiza a=Strift

Fix [Meilisearch 1.18 tests run](https://github.com/meilisearch/meilisearch/actions/runs/17061126416/job/48368042223)

## Summary by CodeRabbit

* **Tests**
  * Updated a JSON-related test to assert the serialized output contains the expected indexes array rather than matching exact JSON, making the test more resilient to formatting differences. No change to behavior or public APIs.

* **Style**
  * Minor indentation/formatting cleanup of test attribute annotations; no functional impact.
