Distinct attribute example

[fharper]

During the livestream @CaroFG said it wasn't really interesting to use faceting distinct attribute with the movies dataset. Is there a way to make it interesting so ALL our documentation examples use the same dataset. If not, is it worth changing all our demos for the one we will have about e-commerce, ref meilisearch/devrel#134. We can also just put a "Warning" in the faceting about the example vs the dataset we provide for tests. In other words, I want to prevent someone trying faceting and not getting interesting results.

It was not faceting @fharper but "distinct attribute". What I said about faceting was that the web interface is not prepared to showcase facets.

Oh, updated the title!

Using a single dataset across all documentation is counterproductive—different features are better illustrated by different use-cases.
