Globals.GetCultureCode will not work when call from scheduler

[zyhfish]

Description of bug

when Globals.GetCultureCode called from scheduler, it will throw out null reference exception, this caused by commit #9ab22767, PortalController.Instance.GetCurrentPortalSettings() doesn't exist in sub thread. i think the code need change to:
var portalSettings = PortalController.Instance.GetCurrentPortalSettings(); cultureCode = portalSettings?.DefaultLanguage ?? Thread.CurrentThread.CurrentCulture.Name;

Affected version

• 9.3.0
