chore: drop PHP 8.3 for php-cs-fixer

Run vendor/bin/php-cs-fixer fix --verbose --ansi --dry-run --config=.php-cs-fixer.no-header.php --using-cache=no --diff
PHP needs to be a minimum version of PHP 7.4.0 and maximum version of PHP 8.2.*.
Current PHP version: 8.3.0-dev.
To ignore this requirement please set `PHP_CS_FIXER_IGNORE_ENV`.
If you use PHP version higher than supported, you may experience code modified in a wrong way.
Please report such cases at https://github.com/PHP-CS-Fixer/PHP-CS-Fixer .
Error: Process completed with exit code 1.
