feat: schedule pre-event notifications job 📆

[rafa1510]

Description ✏️

Closes #478

Describe what this PR does.

• When an event is created, a job is scheduled 2 days before the event to call the function from Infrastructure for Pre-event notifications 🔔  #477
• Note: Function used on sendPreEventNotification needs to be updated when Infrastructure for Pre-event notifications 🔔  #477 is merged. For now there's a console.log statement used for debugging purposes.

Nice work @rafa1510! A lot of the logic for creating the job looks solid, but at a higher level it seems that in this PR we are creating a new worker preEventNotificationWorker to run the job, but we should be able to just add the new job to the existing eventWorker. Let me know if you have any questions on doing this!

This looks really great @rafa1510! Going to mark it for Rami to take a final review. Great work! 🚀

Note for @ramiAbdou: Rafa commented on this but we just have to make sure to merge #524 first
