[Beta 2] Leftover debug code in \applications\core\modules\admin\languages\languages.php

I noticed this code while I was checking the changes from beta 1 in \applications\core\modules\admin\languages\languages.php:

		// This appears inside a dialog. The following instructs the dialog to handle the download via JS rather than using a native form download. This allows the dialog to close when done.
		$filename = $lang->title . " {$lang->version}.xml";
		$form->attributes['data-form-is-download'] = '';
		$form->attributes['data-form-download-name'] = "testing to see if this works " . $filename;

I don't think the testing text string is supposed to be there. 😋
