Remove special treatment of fonts
Currently, Software allows someone to browse for and install fonts. I've come to the conclusion that this is a bad idea, for the following reasons:
- Font search and browsing is quite a specialised thing, and I don't think that Software is invested enough to do a good job of it.
- You get an extremely limited choice of fonts, if they are provided by a distro.
- It assumes that fonts are package-based, which doesn't make sense on immutable operating systems.
- It's yet another type of software that Software has to care about, and adds a bunch of complexity which we'd do well to avoid.
I think we should consider removing the fonts section.
If we care about the fonts experience, we have a Fonts app that we can improve.
