Use (uri (string-append "..."

Why do the files need to be made writable for install?

The description should consist of full sentences.  Note that Nerd fonts
pulls in icons that are licensed under CC BY-NC-ND, which makes them
unfree.  I'm not sure if those icons are present in the default
distribution, but I'd hazard a guess that they are.

More concerningly, the patches that can be applied via nerd fonts are
directly coded into their font-patcher, rather than, say, distributed
as a json file to be read separately.  As far as I'm aware, this makes
nerd-fonts (the tool) itself NG.
