Feature Request: Calendar iCal export: Add setting for disabling topic prefixes on the calendar events

Allow a setting to remove all context from the ical export, and move necessary context to the description of the event.

The calendar event on the export currently is something like:

But I have found myself and other users of my instance wanting it to be more simple, something like:

Maybe the description of the event could have all the context or information about what it is, who is assigned to, etc.

It would be cool to be able to trigger this by event, so for example, maybe I want the chores to be in this short form, but not the meal plan.

Thanks for the great work on grocy
