Add workshops page content

### Background

We need a page that shows the schedule of our workshops, the topics covered, and links to past workshop recordings.

### Requirements

- Add a workshops page with a section featuring a simple calendar widget with meeting dates highlighted and the ability to add to Google Calendar or iCal.
- Add a section for past workshops. This could be a simple scroll view with a list of past workshops, their description, and links to recordings if available.
