[AB3: Removing Fields] Git diff for removing address field

[mfjkri]

Situation

Currently, there is no git diff reflecting the deletion of the address field, which may cause confusion for students.

Problem

Without this information, students might be uncertain if they have correctly deleted the address field as required.

Proposed Solution

Create a commit specifically for deleting the address field and include the corresponding git diff into the guide.

I believe consolidating all the changes into a single commit would be sufficient for this purpose.

@mfjkri Yes, this could be useful.
