commitc846428cb6added proxies to the example `daemon.json`, based on the implementation that was added in427c7cc5f8. However, a follow-up pull request changed the proxy-configuration in`daemon.json` to nest the configuration in a "proxies" struct, and the documentation was not updated accordingly; see:101dafd049This patch fixes the example.
