How to Add Rich Push Notifications in Expo (iOS Images)

A tutorial on implementing rich push notifications with image support on iOS using Expo. Since Android supports images out of the box, the focus is on adding a notification service extension for iOS using the `expo-apple-targets` package by Evan Bacon. The process involves running `npx create-target`, selecting the notification service target, replacing the generated Swift file with one from a reference pull request, running `expo prebuild`, and signing the extension in Xcode. Also covers updating the Expo Server SDK to support the `richContentImage` field when sending notifications from a Node server.
