Path
-p, --path[=PATH]
The --path option allows you to specify the directory where the generated migration files should be created. 
By default, migrations are created in the database/migrations directory.  
Example
To use the --path option, you need to provide the desired directory path. For example:
php artisan migrate:generate --path="custom/migrations"
This command will generate the migration files in the custom/migrations directory instead of the default database/migrations directory.
