Breaking: #107578 - Prepare ext:adminpanel DataProviderInterface change 

Description 

The adminpanel extension provides the interface DataProviderInterface. It can be used by extensions that extend the admin panel with further modules and allows storing additional in the admin panel specific request related store.

The signature of the main interface method has been changed.

Impact 

Extension authors may benefit from the additional argument that is hand over with TYPO3 v14.

Affected installations 

Most instances are not affected by this change since there aren't many known extensions that add features to the admin panel extension. Instances with classes implementing interface \TYPO3\CMS\Adminpanel\ModuleApi\DataProviderInterface are affected.

Migration 

The interface until TYPO3 v13:

namespace TYPO3\CMS\Adminpanel\ModuleApi;

interface DataProviderInterface
{
    public function getDataToStore(ServerRequestInterface $request): ModuleData;
}

Method getDataToStore() is called by the admin panel after the Response has been created by the TYPO3 core. The interface has been adapted with TYPO3 v14 to receive the response from the calling admin panel code:

public function getDataToStore(ServerRequestInterface $request, ResponseInterface $response): ModuleData;

Extension authors aiming for compatibility with TYPO3 v13 and v14 in the same extension version can modify their consumers like this:

public function getDataToStore(ServerRequestInterface $request, ?ResponseInterface $response = null): ModuleData

TYPO3 v13 does not hand over the second argument, so it must be nullable and extensions should not expect to receive an instance of ResponseInterface. TYPO3 v14 however does hand over the instance.
