You are maintaining an Obsidian vault for a software project. The note sprint-tasks.md contains a list of tasks that other notes need to reference individually. Add block IDs to the list items so each one can be linked to from other notes.

Here is the current content of the list section:

## Sprint 3 Tasks

- Implement user authentication
- Set up CI/CD pipeline
- Write integration tests

Write a new version of this section to a file called sprint-tasks-updated.md. Then, in the same file, add a short example showing how another note would link to the second task using a block reference.
