Fix event linking behavior (#46083)

## I have read the
[CONTRIBUTING.md](https://github.com/supabase/supabase/blob/master/CONTRIBUTING.md)
file.

YES

## What kind of change does this PR introduce?

1. Removed the upcoming Figma webinar and postponed it until later
2. Fixed the event linking behavior for MDX events on the page. MDX
events should link to the MDX page, not the CTA.

## Summary by CodeRabbit

* **Updates**
* Event links now intelligently route based on event configuration:
external event URLs open in new tabs when available, while default
events navigate to internal event detail pages within the application
* This provides event organizers with flexible options for directing
attendees to external event platforms or internal event information
pages
  * Event entries updated to support new link routing functionality

-AI prototypes get you from zero to demo fast. But what happens when you want real users? Most AI-generated apps hit a wall the moment you need authentication, persistent data, or row-level security.
-
-In this 45-minute session, Gerardo Estaba, Solutions Architect at Supabase, and Samantha Lee, Designer Advocate at Figma, walk through what it takes to go from a working prototype to a production-ready application. You'll see how to pair Figma Make, Figma's native AI tool for turning ideas into working prototypes, with Supabase's backend to build apps that are secure, scalable, and ready for real user feedback.
-
-### What you'll learn
-
-- Where database-backed AI prototypes bring value
-- How to add authentication and row-level security without rewriting your app
-- How Figma Make and Supabase work together end to end
-- A live build from design to deployed, with a production-grade app
-
-Join us live to participate in the Q&A afterwards. Can't make it to the event? We'll send you a link to the recording.
