Use transparent background for gutter line number in GUI mode (#204)

The `LineNr` and `CursorLineNr` highlight groups now have a transparent
background in GUI mode.

Before it was set to `nord0_gui` which worked fine in most cases.
However, some plugins use these highlight groups to render their content
in a popup window which can potentially have a different background
color. This caused some issues e.g. for the fuzzy search plugin
LeaderF [1].

The compatibility with the `g:nord_cursor_line_number_background`
theme configuration has been verified to work as expected in both modes
when it is set to `0` or `1`.

This change is not related to the terminal mode or when using
`set notermguicolors` since `ctermbg` for `LineNr` and `CursorLineNr`
is set to `NONE` by default.
