Environment
- PHP Version: 8.1
- Database Driver & Version: MySQL
- Migration Actions Version: 3.x
- Laravel Version: 9.x
Issue description
I have a subfolder within my actions folder that does not contain Action classes.. example:

By Running php artisan migrate:actions I get the following error:
DragonCode\LaravelActions\Services\Migrator::resolveAction(): Return value must be of type DragonCode\LaravelActions\Action, int returned
I think files that do not extend Action shouldn't be taken into account or files that don't start with xxxx_xx_xx_xxxxx_..... etc...
Steps to reproduce
Create any file within a subfolder inside the actions directory and run php artisan migrate:actions
