Feature: Dispatch `ModifyTcaSelectFieldItemsEvent` in `TypeItems` and `EmploymentTypeItems`

Description

Following provided itemsProcFunc handlers now dispatches the new PSR-14 \FGTCLB\AcademicBase\Event\ModifyTcaSelectFieldItemsEvent:

\FGTCLB\AcademicJobs\Backend\FormEngine\EmploymentTypeItems
\FGTCLB\AcademicJobs\Backend\FormEngine\TypeItems

Impact

This allows projects to modify the available select items for the backend (FormEngine) and also for the frontend using a PSR-14 event listener:

EXT:my_ext/Classes/EventListener/ModifyJobTypeItemsListener.php

<?php

declare(strict_types=1);

namespace MyVendor\MyExt\EventListener;

use FGTCLB\AcademicBase\Event\ModifyTcaSelectFieldItemsEvent;
use FGTCLB\AcademicJobs\Domain\Model\JobType;

final class ModifyJobTypeItemsListener
{
    public function __invoke(ModifyTcaSelectFieldItemsEvent $event): void
    {
        if ($event->getFieldName() === 'type') {
            $items = $event->getItems();
            $items[] = [
                'Custom Type',
                JobType::CUSTOM_TYPE,
            ];
            $event->setItems($items);
        }
    }
}
