Pivot field and columns on a class' relationship aren't recorded in the models helper

[abodnar]

Versions:

• ide-helper Version: 3.1.0
• Laravel Version: 10.48.20
• PHP Version: 8.2.22

Description:

If you have two classes, say User and FeatureFlag and they have a relationship between them and that relationship specifies an extra column that is on the pivot, it is not recorded for the class when generating the models helper.

Example:

class FeatureFlag extends Model
{
    public function users(): BelongsToMany
    {
        return $this->belongsToMany(User::class)
            ->withPivot('enabled')
            ->withTimestamps();
    }
}

Generated helper for model:

namespace App\Models{
/**
 * 
 *
 * @property int $id
 * @property string $name
 * @property string $flag_type
 * @property bool $enabled
 * @property \Illuminate\Support\Carbon|null $created_at
 * @property \Illuminate\Support\Carbon|null $updated_at
 * @property \Illuminate\Support\Carbon|null $deleted_at
 * @property-read \Illuminate\Database\Eloquent\Collection<int, \App\Models\User> $users
 * @property-read int|null $users_count
 * @method static \Illuminate\Database\Eloquent\Builder|FeatureFlag newModelQuery()
 * @method static \Illuminate\Database\Eloquent\Builder|FeatureFlag newQuery()
 * @method static \Illuminate\Database\Eloquent\Builder|FeatureFlag onlyTrashed()
 * @method static \Illuminate\Database\Eloquent\Builder|FeatureFlag query()
 * @method static \Illuminate\Database\Eloquent\Builder|FeatureFlag whereCreatedAt($value)
 * @method static \Illuminate\Database\Eloquent\Builder|FeatureFlag whereDeletedAt($value)
 * @method static \Illuminate\Database\Eloquent\Builder|FeatureFlag whereEnabled($value)
 * @method static \Illuminate\Database\Eloquent\Builder|FeatureFlag whereFlagType($value)
 * @method static \Illuminate\Database\Eloquent\Builder|FeatureFlag whereId($value)
 * @method static \Illuminate\Database\Eloquent\Builder|FeatureFlag whereName($value)
 * @method static \Illuminate\Database\Eloquent\Builder|FeatureFlag whereUpdatedAt($value)
 * @method static \Illuminate\Database\Eloquent\Builder|FeatureFlag withTrashed()
 * @method static \Illuminate\Database\Eloquent\Builder|FeatureFlag withoutTrashed()
 * @mixin \Eloquent
 */
	#[\AllowDynamicProperties]
	class IdeHelperFeatureFlag {}
}

This leads to Phpstorm not suggesting and tools like Larastan complaining about not finding the fields.
