IMPALA-14552: (addendum) Fix bad testcase in show-create-table.test

The original IMPALA-14552 patch pass precommit tests before
IMPALA-12893: (part 2) (275f03f) merged. As consequence, it does not
catch missing comma in updated show-create-table.test. This patch add
that missing comma.

Testing:
Pass metadata/test_show_create_table.py
