Adding getnf as an option to the README

Is your feature request related to a problem? Please describe

The process of installing the nerd fonts is always a bit of a pain when doing it for the first time. I was recently installing lunarvim and they recommend using ronniedroid/getnf as a simpler way to install nerd fonts.

Describe the solution you'd like

Add an extra line to the readme listing it as an option.

Additional context

I was helping my friend set up their shell for the first time and it was a minor faff explaining how to install nerdfonts on their system. Could be a nice option for people new to linux/shell customization to get started with less friction.
