Some tests still need to fix the format.

What bug does this fix? maybe add a test.

What bug does this fix? maybe add a test.

In fact, there is no bug, and has a higher priority than or (I changed the title).

By adding () can make explain clearer.

Hi @xudong963
Could you add the following logic tests on https://github.com/datafuselabs/databend/blob/main/tests/sqllogictests/suites/task/task_dag_test.test for this PR.

statement ok
DROP TASK IF EXISTS mytaskchild2

statement ok 
CREATE TASK mytaskchild2
  WAREHOUSE = 'mywh'
  AFTER 'mytaskroot'
  WHEN ((SYSTEM$STREAM_HAS_DATA('stream1') AND SYSTEM$STREAM_HAS_DATA('stream2')) OR (SYSTEM$STREAM_HAS_DATA('stream3') AND SYSTEM$STREAM_HAS_DATA('stream4'))) AND SYSTEM$STREAM_HAS_DATA('stream5')
  AS SELECT 1;



query SSSS
select name, warehouse, schedule, definition, condition_text, after from system.tasks where name = 'mytaskchild2'
----
mytaskchild2 mywh NULL SELECT 1 ((SYSTEM$STREAM_HAS_DATA('stream1') AND SYSTEM$STREAM_HAS_DATA('stream2')) OR (SYSTEM$STREAM_HAS_DATA('stream3') AND SYSTEM$STREAM_HAS_DATA('stream4'))) AND SYSTEM$STREAM_HAS_DATA('stream5') mytaskroot
