DDL: add column typo example

[shiyuhang0]

How GitHub App works in this example

This example adds a new field called new_field in the user table. The first commit type the new_field as wrong_new_field and the second commit corrects it.

1. The test in GitHub action will fail in the first commit because of the wrong field name.

2. The test in GitHub action will succeed in the second commit which we fix the bug.

Summarize

In this example:

1. The branch helps us find the wrong DDL in the first commit, and it will not be applied to the production database.
2. We can not execute such a test in a new database without branch. Because the AutoMigrate always loads the whole fields, causing an error in the new added DDL.
