fix: Pass notrigger=1 to updatePrice to prevent SMTP hang

Dolibarr fires internal triggers on price changes which can attempt
to send emails via SMTP. This causes the cronjob to hang indefinitely
when the SMTP connection blocks. notrigger=1 skips these internal
triggers since PreisBot sends its own notifications.
