Create eventbrite event and link it to the page

We need an eventbrite URL to link to the landing page for the tickets

IMO we should keep this for later. Opening the event for registration could happen end of September when we already have a clear structure for the event (where is the hackathon, maybe some speakers already selected, ...)

Ok makes sense so far.
