refactor: use a consistent classname prop and avoid children prop

I was using the FunctionComponent type for some component that do not
use children. So I change the type to VoidFunctionComponent to avoid
mistakes.
I also rename all the "classes" or "additionalClasses" props to
"className" to keep consistency between each components.
