Update security-authorization.md
bump minimum required cubrid version

there is no reliable way to determine the cubrid PDO extension version used
and also no reliable way to detect which combination of server and client produces wrong behavior.

By requiering 9.3 or higher in both client and server we can be sure it works.

fixes #852
bump cubrid pdo version according to #852
UPGRADE note for #852
