[FIX] calendar: Allow any user to set calendar_last_notif_ack

Fixes https://github.com/odoo/odoo/issues/39358
Before this commit Internal user (With no other Rights) cannot perform any activity on Reminder Popup due to missing rights to set calendar_last_notif_ack field.
With this fix, we are now using sudo to write calendar_last_notif_ack
