[BUG 4.7.0] \Helpers\Form\Upload doesn't allow anymore webp images

[teraßyte]

In 4.7.0 the file \system\Helpers\Form\Upload.php now uses \IPS\Image::$imageExtensions instead of \IPS\Image::supportedExtensions() to retrieve the list of supported image formats. Because of this change the webp format is not available anymore.

Thank you, this has been fixed for an upcoming release.
