What are the steps to disable the default migrations for MoonShineUser

1. Open the Configuration File: Locate the `config/moonshine.php` file in your Laravel project.

2. Set the `use_migrations` Option: Find the line that specifies the `use_migrations` option and set it to `false`. This will prevent Moonshine from running its default migrations for the `MoonshineUser` model.

Here is how the relevant section of your configuration file should look:

php
return [
    // Other configurations...

    'use_migrations' => false, // Disable default migrations

    // Other configurations...
];

By setting `use_migrations` to `false`, you can manage your own migrations for user authentication and any other necessary database tables without interference from Moonshine's default setup[1][4].
