Plural missing on CalDAV Activity when creating multiple Calendar events

[anoadragon453]

Steps to reproduce

1. Create multiple events around the same time on Nextcloud Calendar
2. Look at your Activities
3. An activity stating "You created event Event 1, Event 2..."

Expected behaviour

If multiple events are created, activity should read as "You created events Event 1, Event 2..."

Actual behaviour

The word "event" is not plural.

Operating system: N/A
