Bug report: Description not added on the event when using the "Add to Google Calendar" option

Description

When you add a workshop to Google Calendar, the description doesn't show as expected on the calendar, making it challenging for anyone to join the workshop from there.

Step-by-step reproduction instructions

1. Go to the Online Workshops page, and select one of the workshops.
2. Click on Add to Google Calendar.
3. See that the event description has no information at all.

Expected behaviour

I would expect it to create the event with the details for joining it in the descriptions, such as the event information and the link to join it. Maybe also steps for them to contact the team if they need help joining the workshop.

Actual behaviour

While it creates the event, the description only has a broken link with no information at all.

Environment information

• Browser(s) are you seeing the problem on: Chrome Version 114.0.5735.133 (Official Build) (arm64)
• Device you are using and operating system: MacBook Pro (Apple M2 Pro) - macOS 13.4 (22F66)

Start from the Online Workshops page and follow the “Add to Google Calendar” flow described in the reproduction steps. Inspect how the event description and workshop join link are generated; it is done when the created Google Calendar event contains the workshop details and a working join link instead of an empty description and broken link.
