Generated theme does not work in Windows

Bug

The generated theme file does not work in Windows. The theme.ts file that gets generated looks like,

import * as accordionPane from './@dojo\widgets\accordion-pane/accordion-pane.m.css';

export default {
	'@dojo\widgets\accordion-pane': accordionPane
};

Notice specifically the path of the import, ./@dojo\widgets\accordion-pane/accordion-pane.m.css. Those \ characters are causing the import to fail and should be /.

To reproduce, simply use dojo create theme --name test in Windows...
