Export a new util method `getThemesFromGlobals` to easily generate theme with
its variant only by providing a partial globals object. By default it returns
both available theme variants (light & dark). Through options you can prefix
variant property keys, only generate theme with a subset of variant and also
overrides/extend theme.
This repository has been recently transfered from openfun to lasuitenumerique.
We need to fix some paths and urls especially to fix documentation and README
