Toggles should probably never have the 'required' attribute

[SeaPea]

I copied the example code for Toggle elements, which includes the 'required' html attribute, but this doesn't make much sense for a checkbox/toggle and actually behaves differently on iPhone vs Android. iPhone ignores this attribute and works as if the 'required' attribute was not there, but Android treats it as meaning it will only submit the settings if the toggle is 'on' and simply does nothing (not even show a message) if the toggle is 'off' as if the submit button is disabled.

So I would suggest using a different example for the attribute and perhaps not include any html attributes in the example code for Toggles.
