Shared MySQL CDC source doesn't handle timezone correctly

[xxchan]

          Hmmm, this test succeeds in CI, but failed for me locally. `tt1` is ok, but `tt1_shared` has a different result. Any ideas?

failed to run `e2e_test/source_inline/cdc/mysql/mysql_create_drop.slt`

Caused by:
    query result mismatch:
    [SQL] select * from tt1_shared;
    [Diff] (-expected|+actual)

Need someone else to reproduce this. 🙏

To test this locally

1. Add your MySQL to risedev user profile
2. risedev d <profile-with-mysql>
3. risedev slt e2e_test/source_inline/cdc/mysql/mysql_create_drop.slt
