[Meilisearch v1.37.0] Fix networks API tests

Context

Meilisearch 1.37.0 introduces breaking changes to the experimental network API. We want to update this SDK to be compatible with Meilisearch 1.37.0.

Description

Breaking change

The network objects sent to the PATCH /network route must now contain at least one shard object containing at least one remote when leader is not null.

Additions

The network object for routes PATCH /network and GET /network now contains the new field shards, which is an object whose values are shard objects, and keys the name of each shard.

Each shard object contains a single field remotes, which is an array of strings, each string representing the name of an existing remote.

The shard objects in PATCH /network accepts optional fields addRemotes and removeRemotes for convenience:

• pass an array of remote names to shard.addRemotes to add these remotes to the list of remotes of a shard.
• pass an array of remote names to shard.removeRemotes to remove these remotes from the list of remotes of a shard.

For more information, refer to the release notes.

Tasks

• [ ] Update the networks API methods to handle network initialization and update
