Deprecation: #89468 - Deprecate injection of EnvironmentService in Web Request

See Issue #89468

Description

The EnvironmentService is not needed any longer in the Web Request of Extbase, therefore the property and the injection method of said property have been marked as deprecated.

Impact

As of TYPO3 11.0, the property \TYPO3\CMS\Extbase\Mvc\Web\Response::$environmentService will no longer exist. If the environment service is needed in a subclass of \TYPO3\CMS\Extbase\Mvc\Web\Response, it needs to be injected manually.

Affected Installations

All installations that implement subclasses of \TYPO3\CMS\Extbase\Mvc\Web\Response and expect an instance of the EnvironmentService`to be injected into :php:TYPO3CMSExtbaseMvcWebResponse::$environmentService`.

Migration

The environment service needs to be injected manually in the subclass.
