This config allows you to override the Question Editor API labels.
This feature can be used for internationalisation or simply for tailoring QE to use phrases your authors are accustomed to. You can also
specify placeholder labels in the label bundle.
To make it easy to set labels, you can use the debug flag (see below) which will show the path for each of the labels in the widget.
Any labels you omit from the label_bundle config will use the default value.
