Use correct location of global config for Nim

Correct path is listed here (See number 2).

While it says nim.cfg in the docs, config.nims is the correct file for this purpose

OK, but that confused me. Is that the official documentation plainly wrong and needs fixing?

Oh sorry should've been more specific.

Basically .cfg is a basic config type that doesn't let you run Nim code (which the example in the readme uses)
But both are valid config file types
