feat: windows app icon (#3753)

* default icon

* cli

* fix typos, fmt + icon fix

I don't think it's a good idea to do
[default.extend-words]
fo = "fo"

 as it's a very common mispelling for 'for'

* fix clippy

* return error on non implemented platforms instead of default dx icon

* fix

* fix

fix the amazing merge
renamed winres to windows
moved windows winres build request to windows

* fix typos

* fix schema

* Update schema.json

* fix schema again

* use default icon if no fallback

* wire up the rest of windows

* fmt
