Replace all `map[string]interface{}` by the type created for this purpose `Unknow`

[alallema]

An "unknown" type is available in the type list but it has not been used or very little in this SDK. It could be great and cleaner to replace all the map[string]interface{} with Unknow

// Unknown is unknown json type
type Unknown map[string]interface{}

I can work on this issue, but it shows Version dependency

Hi @alallema, should a PR closing this issue change the types of the public APIs too or should changes be limited to internal uses of map[string]interface{}?

i.e. should something like GetRawIndex return meilisearch.Unknown instead of map[string]interface{}?

I imagine those might be considered breaking changes?

Hi @a11rew, Thanks for the question, indeed I was just thinking of changing the internal type only to avoid breaking and not forcing people to use our specific type.
