Broken link for journaling API in `Option 1: Using Journaling API to consume events` section

Issue in /src/pages/resources/event-driven/lesson4.md

The paragraph https://developer.adobe.com/app-builder/docs/resources/event-driven/lesson4/#option-1-using-journaling-api-to-consume-events has url reference to journal api which is not found now.

Please update the docs to reflect the correct url reference for journaling API.

Open /src/pages/resources/event-driven/lesson4.md and find the “Option 1: Using Journaling API to consume events” section. Identify the outdated Journaling API URL, replace it with the correct reference, and verify that the link resolves from the rendered documentation page.
