IGAPP-1177: Enable export of recurring events

The export of a single event is currently possible (see linked Issues). But the user should be able to export recurring events as a single iCal event. This can be realized through a recurrence rule, see https://icalendar.org/iCalendar-RFC-5545/3-8-5-3-recurrence-rule.html Consider how recurring events are represented in the cms. See https://icalendar.org/iCalendar-RFC-5545/3-8-5-3-recurrence-rule.html

Corresponding CMS issue: https://github.com/digitalfabrik/integreat-cms/issues/1965

 Note: this should happen for both web and native.

The CMS API now combines the recurring events when accessed with the combine_recurring parameter: https://cms.integreat-app.de/testumgebung/de/wp-json/extensions/v3/events/?combine_recurring=1
