"'audion' started debugging this browser" warning stays after DevTools are closed

[max-vogler]

Even after closing Dev Tools or clicking "Cancel", the warning bar is still shown. This comes from audion re-attaching here:

audion/src/devtools/WebAudioEventObserver.js

Lines 30 to 37 in ad80955

	const onDetach = () => {
	chrome.debugger.attach({tabId}, debuggerVersion, () => {
	chrome.debugger.sendCommand(
	{tabId},
	ChromeDebuggerWebAudioDomain.Methods.enable,
	);
	});
	};

Both possible DetachReasons are user initiated, so I think removing the re-attach logic is sensible.
