Better docs for field callback functions

[distantnative]

'myNumberField' => function ($model) { 
    return $model->myNumberField()->toFloat();
}

'myVirtualNumberField' => function ($model) { 
    return $model-> myNumberField()->toInt() + 5;
}

'myDate' => function ($model) { 
    return $model-> anyDateField()->toTimestamp();
}

especially pointing out how they can be used for different formats for Algolia
