Fix abstract method error

Problem/Motivation

Fatal error: Class Drupal\Core\Database\Driver\autoslave\Connection contains 1 abstract method and must therefore be declared abstract or implement the remaining methods (Drupal\Core\Database\Connection::open) in /var/www/html/core/lib/Drupal/Core/Database/Driver/autoslave/Connection.php on line 53

Steps to reproduce

on Drupal 9.5.9

Proposed resolution

Apply abstract method

Data model changes
