💄(react) do not apply font-family to all elements with * selector

Currently, `react` package use `*` selector to enforce the font family
to all elements. That is weird as all elements are not able anymore to
inherit their font-family from their parent. In order to enforce the use
 of font-family base by default without breaking the parent inheritance,
  we apply font-family to the body element instead.
