Fixes #5528: added auto_reload to default twig config in both extension readme and template engines chapter in docs

Shouldn't stability=dev be removed?

changed  $query->from(['author' => 'users'])  to  $query->from(['author' , 'users']) on line 354

close #5527

Possible typo.

close #5526

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
