Set names in site.webmanifest for PWA

Resolves kiwix/kiwix-tools#799

[rgaudin]

I don't think this is the right move. kiwix-serve is a tool to serve a content catalog. That catalog should have a name and that should not be “Kiwix” which is already overused and confusing. Add to that the fact that we have https://library.kiwix.org which is The Kiwix Catalog…

This should follow #915 IMO.

[Roan-V]

Your point is certainly fair, but #915 looks pretty stale for now
I'd argue that (at least as a stopgap) "Kiwix" is preferable over letting the browser picking a default name. Firefox turns it into "Web site" for example

When #915 gets more progress this could quite easily be changed again
Don't let perfect be the enemy of good decent and all that :P

I maintain that Kiwix is a terrible value. If we want to improve without fixing we should make it obvious that it's a generic name from a tool because those metadata are supposed to reference a content source.

"kiwix-serve instance" would work.

Given we recommend kiwix-serve to be behind a reverse proxy for public access cases, overriding it there would be a possibility
