Export components props at root level

[itofarina]

Problem

Right now we are not exporting the interfaces that define the props needed by the components. So for example when using the library and want to import the TooltipIconButtonProps, the user needs to do import { TooltipIconButtonProps } from '@rsksmart/rif-ui/dist/components/molecules/TooltipIconButton'.

Solution

Export types at root level so users can do import { TooltipIconButtonProps } from '@rsksmart/rif-ui
