Drivers section appears to be out of date.
Starting in drupal:9.4.0 the stated architecture for the core drivers is deprecated. It is removed from drupal:11.0.0. For example The MySQL database driver has been moved to the core mysql module, so that its namespace is now Drupal\mysql\Driver\Database\mysql. See

# Drivers
Because different databases require different sorts of interaction, the Drupal database layer requires a driver for each database type. A driver consists of a series of files located in a module named for one specific database type. For example the core "MySQL" driver core is a series of files located in the mysql module, at core/modules/mysql/src/Driver/Database/mysql, where driver is a string representing the unique key for that driver. Each of the other core database drivers is structured likewise, and located in its own named module, i.e. "pgsql" , and "sqlite". Contrib database drivers may be added to extend core functionality, in their own module's namespace and "src" directory.
## Namespace considerations
Each driver consists of several classes derived from parent classes in the core database system. These driver-specific classes may override whatever behavior is needed to properly support that database type. Driver-specific classes are always namespaced for their database type. For example, the MySQL specific version of Insert is within the Drupal\mysql\Driver\Database\mysql namespace.
