Developer tools for extensions is failing for preview

It is failing on all three platform. Looks like there is a configuraiton issue:

@Sam_Horvath @jcfr

@lassoan changed out the icon ExtensionStats.png for ExtensionStats.svg in Fix ExtensionStats copy to table · Slicer/SlicerDeveloperToolsForExtensions@bbe7eec · GitHub which caused the configuration error of the ExtensionStats module.

The icon has been fixed, let me know if there are still issues.
