nvim: Switch to gruvbox8

Back at this again as it loads faster and did not realise last time that
the background can be over ridden with an auto command group to be set
to complete black. The auto command group must be read first before
setting of the color scheme that's why the autocmd file is now loaded
first before everything else.
