That's a lot of work on this one, I'll review it as well. Thanks!
How did you proceed to update the it to 5.15.2?

Also out of curiosity, do you know why the fa has been replaced by fas, far, fab? Maybe I should go read about the differences between v4 and v5.

They splitted the icons in different fonts: solid, regular and brands. FA 4 had 675 icons, FA 5.15.2 have 1609 free icons and 7865 pro icons.

About how I proceeded. I did a similar update in December 2019 but did not made a PR at the time so I had an idea of what to do. I screened the theme files to understand how you implemented and the FA documentation to see what should divert from it or could be improved. I deleted the old FA .scss and fonts from the repo and copied the 5.15.2 in the place. As syntax slighted changed I had to replace fa accordingly by [fas,far,fab]. I used ripgrep to find the files that I had do edit and in some used vim/sed to search and replace the strings. Then tested to see if I missed something.

I though on using svg sprites instead of the fonts, as I did in the past but that would divert a lot more from what was currently being used and require an additional JS script to be loaded.

Also some icons might have been missed as they are not rendering for me.

For example far fa-file-text:

Also, the share icons seems to still have fa like the facebook one fa fa-facebook-square fa-2x causing them I suppose to not be rendered.

Fixed those.
