Documentation not updated after refactoring

[JaGeo]

I just spotted some issues in the documentation:

https://autoatml.github.io/autoplex/user/phonon/flows/fitting/fitting.html#gap

Here, "num_processes_fit" should not be part of the make but of the initialisation of the code.

Honestly, I don't see a num_processes_fit in a make call. Was the issue already taken care of?
