[1.x] Make PulseMigration compatible with Laravel v12.4: public shouldRun()

[onlime]

In Laravel v12.4.0 laravel/framework#55011, the following method was added to Illuminate\Database\Migrations\Migration:

    public function shouldRun(): bool
    {
        return true;
    }

so Laravel v12.4.0 breaks Pulse:

  In PulseMigration.php line 25:                                                                                                                                     
                                                                                                                                                                     
    Access level to Laravel\Pulse\Support\PulseMigration::shouldRun() must be public (as in class Illuminate\Database\Migrations\Migration)                              

This PR fixes it.

I had this issue also.

I think your PR description should say that function shouldRun() was added rather than function getConnection()
