dm: import_v10x Test Case Fails in DM CI Due to Recent Changes in TiDB

[wlwilliamx]

What did you do?

I submitted a PR to the TiFlow repository, but one of the DM test cases in the GitHub CI, import_v10x, keeps failing. The failure is caused by recent changes in TiDB, specifically in how the default int type is displayed when executing the SHOW CREATE TABLE statement. ref: pingcap/tidb#56529

What did you expect to see?

import_v10x test passes.

What did you see instead?

import_v10x test failed.
