What does this Pull Request (PR) do?

Updates Fantasque Sans Mono to 1.8.0.
I updated the src/unpatched-fonts, as well as the license (copyright year update) and the readme, then ran the script to update everything.

How should this be manually tested?

I installed the fonts on my Mac and they seem to work. Interestingly I did see one error with the italic variant:

But the font still appears to work fine.

Any background context you can provide?

What are the relevant tickets (if any)?
