General: Remove all fold markers.

[dylanaraps]

Description

This PR removes all vim fold marker comments that littered neofetch and stops enforcing a fold method for people editing the file.

Instead I recommend using bash syntax folding with the following settings in your .vimrc:

filetype plugin indent on
augroup Bashfold
    au!
    autocmd Filetype sh let g:sh_fold_enabled=3
    autocmd Filetype sh let g:is_bash=1
    autocmd Filetype sh setlocal foldmethod=syntax
augroup END
syntax on

autocmd Filetype sh let g:sh_fold_enabled=3

The 3 will set vim to only fold functions. Raising this number will make vim fold if statements and etc.
