Make it clear DocHub is a student initiative (and open to contributions)

Specify better that students are behind DocHub and that you can actively contribute to it.

Relates to #199 (maybe we should close one of the other)

How can we do that ? Usually writing a block of text on the homepage does not yield good results as people tend to ignore it and it takes valuable place after they hypothetically read it. I think we have to find a clever way to do better.

The logo of the CI is quite know for being a student thing maybe we could try to put the logo of dochub with a little by CI (with their logo) it bottom left ?

We got an email from Gérald asking for

pourriez-vous adapter la page d’entrée de dochub en indiquant que vous n’êtes pas une source institutionnelle et que les documents officiels sont dispo sur les plateformes institutionnelles telles UV, MonULB, …

We should plan this soon :)

Changing the text would probably not be enough since most student don't take time to read it. And the background similar to the ulb one would not help
