[Bug]TimeoutError in test_TC_TIMESYNC_2_1 due to CancelledError in Read operation.

[Rajashreekalmane]

Describe the bug

The test_TC_TIMESYNC_2_1 test case fails with a TimeoutError due to a CancelledError occurring during the Read operation. This seems to be caused by the operation taking longer than the allowed timeout, leading to the cancellation of the task.

[MatterTest] 08-16 06:58:32.248 ERROR Exception occurred in test_TC_TIMESYNC_2_1.

The above exception was the direct cause of the following exception:

Steps to reproduce the behavior

1. Open the UI
2. Upload the PICS
3. Ensure the TC_TIMESYNC_2_1 test case is selected
4. Executed the below mentioned command to put DUT into a commissionable state, ./chip-all-clusters-app
5. Click the Start button on Test-Harness user interface.

Expected behavior

The test_TC_TIMESYNC_2_1 test case should successfully execute without encountering any TimeoutError or CancelledError
