1186: Changes related to the next Meilisearch release (v1.3.0) r=bidoubiwa a=meili-bot

Related to this issue: meilisearch/integration-guides#280

This PR:
- gathers the changes related to the next Meilisearch release (v1.3.0) so that this package is ready when the official release is out.
- should pass the tests against the [latest pre-release of Meilisearch](https://github.com/meilisearch/meilisearch/releases).
- might eventually contain test failures until the Meilisearch v1.3.0 is out.

⚠️ This PR should NOT be merged until the next release of Meilisearch (v1.3.0) is out.

_This PR is auto-generated for the [pre-release week](https://github.com/meilisearch/integration-guides/blob/main/resources/pre-release-week.md) purpose._
