[TASK] Allow execution with PHP8.5 in Build/Scripts/runTests.sh

PHP8.5.0alpha1 has been released [1] recently and official php
docker image made available with [2], which allowed us to build
`ghcr.io/typo3/core-testing-php85` image based on it [3][4].

This change allows PHP8.5 to be used as option for the dispatch
wrapper `Build/Scripts/runTests.sh` to start testing locally.

Adding to pre-merge and/or nightly will be done later when it
has been proofen to work.
