This change raises the dev dependency PHP-CS-Fixer
to 2.19 (forward-compatible to 3.0) and 3.0,
allowing to run PHP-CS-Fixer with PHP8.

This change adapts the config file to use
the latest syntax. Using PSR-12 will be
handled in a separate followup.

Used composer commands:
- composer req friendsofphp/php-cs-fixer:"^2.19 || ^3.0" --dev
- composer req friendsofphp/php-cs-fixer:"^2.19 || ^3.0" -d typo3/sysext/core --dev --no-update
