[Enhancement?] gnome-builder

[VentGrey]

Since obsidian is being based on Faenza, the current gnome-builder icon does not seem very "explainatory" all by itself.

I suggest maybe using the same background but without the gear and a more "robot-arm" icon
I'm no editing expert but this is an idea I've got, maybe someone agrees with me :B

Hope no one notices i just pasted the icon in there.
