Breaking: #107783 - Registration of metadata extractors via registerExtractionService 

Description 

The method \TYPO3\CMS\Core\Resource\Index\ExtractorRegistry::registerExtractionService() has been removed in favor of automatic registration via the interface \TYPO3\CMS\Core\Resource\Index\ExtractorInterface .

Registration of metadata extractors now happens automatically when a class implements the required interface ExtractorInterface . No further registration is necessary.

Impact 

Any call to ExtractorRegistry::registerExtractionService() is now a no-op and has no effect in TYPO3 v14.0+. Metadata extractors are automatically registered via the interface.

Affected installations 

TYPO3 installations with custom extensions that register metadata extractor classes via the mentioned method in ext_localconf.php.

The extension scanner will report such usages.

Migration 

The method has been removed without deprecation in order to allow extensions to work with TYPO3 v13 (using the registration method) and v14+ (using automatic interface-based registration) without additional deprecations.

Remove the manual registration from ext_localconf.php:

- $extractorRegistry = GeneralUtility::makeInstance(ExtractorRegistry::class);
- $extractorRegistry->registerExtractionService(MyExtractor::class);

Since custom extractors already implement the required interface ExtractorInterface , no further changes are required inside the extractor class itself.
