[Editor.Spacemacs] Replace "turn-on-fci-mode" with Better Wrapper
[Editor.Spacemacs] Replace "turn-on-fci-mode" with Better Wrapper

Fix #3, the functionality provided by package "fill-column-indicator" has now
been implemented natively in Emacs as "display-fill-column-indicator-mode", and
available from version 27.0.90.

Spacemacs running on these version Emacs won't install package
"fill-column-indicator" any more, so function "turn-on-fci-mode" won't exist.
