Ajouter logo MathOA avec lien dans Footer (ou ailleurs)

"A mention with logo in the grey bar at the bottom of https://mrr.centre-mersenne.org/ and all other pages would serve well. This could be on either side of Centre Mersenne. I am happy to let you exercise your preference in this respect. The appearance would be analogous. “Publisher:” followed by the logo (from https://www.mathoa.org/), which is a link to https://www.mathoa.org/about/"
