Make model factory method annotation optional in phpDoc

[sanfair]

Summary

Laravel v11.15.0 added generic support for the model factories (https://github.com/laravel/framework/pull/52005)

If you use the \Illuminate\Database\Eloquent\Factories\HasFactory trait with generic annotation, factory annotation in the class's phpDoc becomes redundant.

Proposal

Make factory generation optional (ideally in the config).

Probably add additional condition between the next lines: https://github.com/barryvdh/laravel-ide-helper/blob/591e7d665fbab8a3b682e451641706341573eb80/src/Console/ModelsCommand.php#L1333-L1339
