Update official documentation needed (Programming guide)

In the official documentation -> Programming guide -> Class Creation Basics -> c++ Only

some stuff doesn’t exists anymore :

UPointLightComponent don’t have Brightness anymore.

Components don’t exists anymore.

It’s not big problems, but it could be cool if it’s can be update.

Also i don’t know if it’s has been already reported so sorry if it is.

Thanks and continu your great job !
