Description
As of PHP 8.5, accessing driver specific PDO constants through PDO is deprecated; see https://wiki.php.net/rfc/deprecations_php_8_5#deprecate_driver_specific_pdo_constants_and_methods. The preferred way is to refer to the corresponding driver subclass for such constants; see also https://wiki.php.net/rfc/pdo_driver_specific_subclasses.
As far as I can see, this is limited to the usage of PDO::MYSQL_ATTR_SSL_CA, which should be replaced with \Pdo\Mysql::ATTR_SSL_CA. However, with the latter requiring PHP 8.4+, some backwards compatible implementation will be required. I'm willing to provide a fix, but am wondering on how to approach this.
Steps To Reproduce
Running e.g. tests will yield a message
