[SPARK-29108][SQL][TESTS][FOLLOWUP] Comment out no use test case and add 'insert into' statement of window.sql (Part 2)

### What changes were proposed in this pull request?
When I running the `window_part2.sql` tests find it lack insert sql. Therefore, the output is empty.
I checked the postgresql and reference https://github.com/postgres/postgres/blob/master/src/test/regress/sql/window.sql
Although `window_part1.sql` and `window_part3.sql` exists the insert sql, I think should also add it into `window_part2.sql`.
Because only one case reference the table `empsalary` and it throws `AnalysisException`.
```
-- !query
select last(salary) over(order by salary range between 1000 preceding and 1000 following),
lag(salary) over(order by salary range between 1000 preceding and 1000 following),
salary from empsalary
-- !query schema
struct<>
-- !query output
org.apache.spark.sql.AnalysisException
Window Frame specifiedwindowframe(RangeFrame, -1000, 1000) must match the required frame specifiedwindowframe(RowFrame, -1, -1);
```

So we should do four work:
1. comment out the only one case and create a new ticket.
2. Add `INSERT INTO empsalary`.

Note: window_part4.sql not use the table `empsalary`.

### Why are the changes needed?
Supplementary test data.

### Does this PR introduce any user-facing change?
No

### How was this patch tested?
New test case

Closes #27439 from beliefer/add-insert-to-window.
