ysql: fix select from wrong table in array_op_test

Summary:
This was supposed to land in upstream postgres first, but it seems to
have been swept under the rug.  See discussion
<https://www.postgresql.org/message-id/20210610232915.19587-1-git%40jasonk.me>.

The original message:

In the middle of GIN index testing, there are some selects that are on
a different table array_op_test that doesn't even have an index.  They
probably were supposed to be selects to table array_index_op_test like
the other ones around the area.

Fix that.  The expected output should stay the same because both tables
use the same array.data.
