Update all projects urls
Make sure that all projects / cubes url targets the new forge (and not the old one).
cf https://forge.extranet.logilab.fr/cubicweb/cubes/signedrequest/-/blob/branch/default/cubicweb_signedrequest/__pkginfo__.py#L29 for instance.
To upload designs, you'll need to enable LFS and have an admin enable hashed storage. More information
