Consistent `Error` and `MoreMsg` highligh. in term and GUI mode (#202)

Before the `Error` group in GUI mode used `nord0` as foreground color
instead of `nord4` resulting in a bad contrast.

Also since there was also no color defined for terminal mode for the
`MoreMsg` group (see `:help MoreMsg` that link to `:help more-prompt`)
Vim used the default color which was some kind of green.
To ensure it matches Nord's style it has now been changed to use `nord8`
(main accent color) for both terminal and GUI mode.
This can be tested by running `:echon "MESSAGE\n"` taht produces a lot
of lines that won't fit on the current screen space anymore.
