Feature request - Add social sharing previews to events/<event-slug> pages

**Is your feature request related to a problem? Please describe.**
When users share events on social platforms, it would enhance the Junction brand value if the event links, eg. https://eu.junctionplatform.com/events/junction-2023 , had a preview that can show info about the event and the event logo, as it would allow users to post event links without any extra context needed, as the preview would cover that already

**Describe the solution you'd like**
Add `og:<...>` metatags to /events/ pages

**Additional context**
Currently, the event links have no preview
