### Describe the bug

Amplify auth update' resets the modified function code used by auth module amplify/backend/function/AdminQueriesXXX/src.

### Expected behavior

The modified function code should not be reset.

### Reproduction steps

1. Init Amplify project.
2. Add auth with admin queries as per the documentation
3. Change code of the function 'amplify/backend/function/AdminQueriesXXX/src'.
4. update api -> 'amplify update auth'
5. Change the auth parameters e.g. add user pool groups.
6. Local code of the function is rewritten with template code. check 'amplify/backend/function/AdminQueriesXXX/src' to confirm that previous code changes are reset.

### Additional information

_No response_

Start by reproducing the documented sequence with amplify/backend/function/AdminQueriesXXX/src: edit app.js, run amplify update auth, and compare the local function code before and after the update. Trace the auth update and Admin Queries template generation paths to identify why the existing code is replaced; done means local changes remain intact after changing auth parameters.
