Ensure this SDK follows the following guidelines:

• All the errors > 400 without message should be sent as MeilisearchCommunicationError
• Know errors like index is not found, or mistakes in the request like not-allowed params should be sent as MeilisearchApiError
• Any other error should be a MeilisearchError

Essentially all the error should extend from MeilisearchError, the consumers should have a way to catch all the errors.
Let us know if this is not clear, or you have better idea!

TODO:

• Create a base error called MeilisearchError which will extend the standard error if it does not exist (when the language supports)
• Make all the other errors extend this error.
• Move all errors without message to MeilisearchCommunicationError since it is not a Meilisearch error anyway.

This issue has been fixed, but I don't have track of which PR did 😅
