Use devdocs icon

[cmalard]

Hello there,

Is there any reason for the current icon being different than the devdocs one ? :-)

• https://github.com/Thibaut/devdocs/tree/master/public/images

hmm cuz I didn't know about that 😅

I think I won't use that icon cuz this is not the official desktop client of devdocs.io.
