Fixes an issue where exec-shell-from-path could not be installed on
Linux or Windows.

Doom used :ignore because, at the time, it supported a workflow where
your Emacs config was shared over dropbox or rslsync across multiple
computers. This workflow is no longer supported (it was very buggy!), so
this is no longer necessary. :ignore should also be reserved for private
use and not used internally.
