Breaking: #110211 - Raise minimum PHP version to 8.5 

See forge#110211

Description 

The minimum PHP version required to run TYPO3 has been raised to PHP 8.5.

Impact 

The TYPO3 Core codebase and extensions tailored for this version can use features implemented with PHP up to and including 8.5. Running TYPO3 with older PHP versions will trigger fatal errors.

Affected installations 

All installations running a PHP version lower than 8.5.

Migration 

Update the PHP platform to PHP 8.5 before upgrading to this TYPO3 version. Previous TYPO3 versions already support PHP 8.5, which allows upgrading the PHP platform in a first step and TYPO3 in a second step.
