changes on d.o. like event-dates are not updated on drupical

Problem/Motivation

see issue https://www.drupal.org/project/drupical/issues/3413851 → as a reference.
We have to check why the node on drupical was not updated.

Proposed resolution

investigate first if there was an errror (node was nearly 2 years on d.o. not updated or check how we handle date/time, location, title etc updates in drupical backend.

Remaining tasks

if needed, implement an update process/step to avoid this problems in the future
