Use up-to-date version of scratch-storage

[benjiwheeler]

www is on an old version of scratch-storage.

gui is on a current version of scratch-storage.

it sounds like www's version doesn't really matter, but maybe we should update it? And configure dependabot to keep it up to date?

Note that dependabot will no longer auto-merge; we either have to install another CI or have devs that monitor deps. scratch-storage version mismatch is probably because at some point it bumped major version.

WWW currently uses scratch-storage, but it's just for getting the used extension/cloudvar/"username" block. Probably the best option is to bump scratch-storage and make it peerDeps, or alternatively, to remove project loading from scratch-storage and make it GUI/WWW stuff.
