Module displays incorrect version

This version pattern in src/ContentSyncHelpManager.php doesn't seem to work correctly. Should the '5' be a '\d'?

$version = (isset($module_info['version']) && !preg_match('/^8.x-5.\d+-.*-dev$/', $module_info['version'])) ? $module_info['version'] : '8.x-1.x-dev';
