Clarify facet distribution behavior when using exhaustive pagination

[Many the fish]

The exhaustive pagination documentation, precise that totalHits and totalPages are exhaustive:

If you set page to 0, Meilisearch processes your request, but does not return any documents. In this case, the response body will include the exhaustive values for totalPages and totalHits.

But this exhaustivity is true for the facetDistribution too.
We may add a precision about the facetDistribution behavior when using page and/or hitPerPage

See you!
