🌟subscribable ICS calendar for public organizer page

[shrippen]

Is your feature request related to a problem? Please describe.
We are organizing workshops as part of our community. It is possible to see all upcoming events on the webpage of the organizer but it would also be nice if the events could be available as a subscribable ICS calendar for everyone in our community to subscribe to if they want.

Describe the solution you'd like
A new button on the organizer page offering an ICS calendar.
