DM: ignore-checking-items does not work as intended

[OliverS929]

What did you do?

Specify ignore-checking-items: ["auto_increment_ID"] in DM task configuration file

What did you expect to see?

ignore precheck items on "auto_increment_ID"s

What did you see instead?

Still receive errors "sourceID %s table %v of sharding %s have auto-increment key, please make sure them don't conflict in target table!", sourceID, table, c.targetTableID

Versions of the cluster

DM version (run dmctl -V or dm-worker -V or dm-master -V):

v8.5.1

Upstream MySQL/MariaDB server version:

TBD

Downstream TiDB cluster version (execute SELECT tidb_version(); in a MySQL client):

v8.5.1

How did you deploy DM: tiup or manually?

tiup

Other interesting information (system version, hardware config, etc):

Indeed. However I would like to double check here whether auto_increment_ID is the only item that does not work with the ignore settings.
