Deprecation: #99558 - Deprecate PageRepository->getExtURL()

See forge#99558

Description

The method \TYPO3\CMS\Core\Domain\Repository\PageRepository->getExtURL() has been marked as deprecated and should not be used any longer.

Impact

Calling the method triggers a deprecation level log message since TYPO3 v12 and will stop working in v13.

Affected installations

PageRepository->getExtURL() is a detail method and relatively unlikely to be used by extensions. The extension scanner will find affected code places.

Migration

The method has been discontinued and there is no direct migration.

If needed, the most simple solution is to copy the method to an extensions code base and maintain it within the extension.
