Build the first draft of the new brand page WD-1343

[ClementChaumel]

Done

• Added the content for the new brand page
• Updated the footer to include the new navigation

It's pretty early stage and the spacing is all over the place but it's all I could do with the miro wireframes

Wanted to merge it, but it's in conflict again. And I think it's still a Draft.

Also, I think we don't have enough content to justify such footer:

It looks empty and just repeats what we have in top navigation. I think I'd just remove that.

It's the case on every page but the padding on the row makes things a bit unaligned
