Took the time to upgrade my #neovim config. Completely scratched the old one.

There were two major things I learnt:

1. It is a pain to setup neovim on a shared directory. Best to ignore the suggestion altogether and multi install it for every separate user.
2. When using #NerdFont in the config, one needs to update one's terminal with that font version plus assign it. Didn't realize that one cannot setup a new font just for neovim like one can do with #vim

The main upgrade consisted of using a pre-built config written completely in #lua.
