Subject: [PATCH] [regression](case)fix mc regression test p2 case. (#42217)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Proposed changes
In previous versions, use a db that does not exist in show databases
will not cause an error, so this test can be run before.

Since the test account does not have the list all projects permission,
there is no db want to be used when show databases， which causes the
case to fail.

Therefore, creat a new catalog and specify `mc.default.project` to fix
this case.
