Use alternative image with newest version

IRC we needed the development branch for PHPCS support for PHP8.4, PHP8.4 support is still not backported (even now PHP8.5 is out).

We switch to another image as we now install the tool ourselves in our image. We used the default container as it would make maintenance easier
but now we needed to patch the composer.json a couple of times so doing this ourselves from the start is easier.
