speed up TestEventSourceManagerRun (#26262)

- `setting.UI.Notification.EventSourceUpdateTime` is by default 10
seconds, which adds an 10 second delay before the test succeeds.
- Lower the interval to reduce it to at most 3 second delay (the code
only send events when they are at least 2 seconds old).

(cherry picked from commit 3adb9ae6009ff3ddebaed4875e086343f668ef7b)
