Update Font Awesome to the latest version
#  I would like to get the new font v6 icons added to nerd fonts

Hi, have heard that it's problematic to move to newer version of nerd fonts, because the code points change, and or are not clustered.
But I have also noticed, that font awesome also ships SVGs, and like with octicons, we can use a script to patch the SVGs in.

The new font awesome icons are much more useful. They have a lot more computer/programming oriented icons, and also allow for multiple styles.

I had noticed this problem, when I couldn't find any icons on the cheat sheet with a RAM icon, and it is available here, on font awesome: [click](https://fontawesome.com/icons/memory?f=classic&s=solid), and in multiple different styles.

## Concerns
1. There is no space for new code points in the font awesome range
   Because the icons are shared in SVG, and are named, we can leave existing icons in the existing range, and create a new, bigger range for the rest of the icons, and avoid duplication.
2. How will we update in the future, when more icons are added to font awesome?
   We can make the new range significantly bigger (I am talking multiple 10000+ spaces (there are 2000+ open source icons from font awesome rn)), so we allow for updates
3. Won't it become unusable and slow?
   Right now the `solid` style of font awesome with all the icons is 1m. But ttf format is fully capable of managing large files,  Some Chinese/Japanese fonts are up to 50M in size, and it all works well
