Hi 20degree,
In case you offer a version of Bforartists to other people, then you must give your customers a way to get access to the source code too, yes. This is the very nature of GPL.
But it is not necessary as long as this file is just for your personal use. And in case of a unmodified version, when you just mirror the official Bforartists installer, then you could simply point to the Bforartists github repository.
I hope this answers your questions.
Kind regards
Reiner
