Wrong namespace used for core's MySql schema class

Problem/Motivation

The Drupal\dbxschema_mysql\Database\Schema class extends Drupal core's MySql schema class, but this currently results in a fatal error due to a wrong namespace used:

use Drupal\mysql\Database\Driver\mysql\Schema as MySchema;

Core's class uses this namespace: Drupal\mysql\Driver\Database\mysql (see different positions of Database and Driver).

Steps to reproduce

• Check use statement for core's MySql schema class in Drupal\dbxschema_mysql\Database/Schema class file and compare to core's MySql schema class namespace

Proposed resolution

• Fix use statement to use correct namespace

Remaining tasks

• Create issue fork and MR to fix this issue
