Replace deprecated call to deprecated method getFromDriverName() of class Drupal\Core\Extension\DatabaseDriverList

Problem/Motivation

As (soon to be) discovered by mglaman/phpstan-drupal 1.2.0 (see 📌 Bump mglaman/phpstan-drupal to latest to make daily "updated deps" QA run pass again Fixed ), we are using some deprecated functionality throughout Drupal core.

This issue is for dealing with:

  Line   core/includes/install.core.inc

  975    Call to deprecated method getFromDriverName() of class          
         Drupal\Core\Extension\DatabaseDriverList:                       
         in drupal:10.2.0 and is removed from drupal:11.0.0. Use         
           DatabaseDriverList::get() instead, passing a database driver  
         namespace.

Note: Depending on the landing of 📌 Bump mglaman/phpstan-drupal to latest to make daily "updated deps" QA run pass again Fixed before the landing of this issue, we also might need to remove two suppressions from core/phpstan-baseline.neon

Steps to reproduce

Proposed resolution

Upon closer inspection, both calls detected above were added/changed in ✨ Introduce database driver extensions and autoload database drivers' dependencies Fixed to accommodate the deprecations in that issue.

Let's keep these two suppressions in the baseline until they will disappear in d11.0.0.

Remaining tasks

User interface changes

API changes

Data model changes
