Describe the bug
Drupal 11.2 converts requirements severity to enums.
Here is change record: https://www.drupal.org/node/3410939
Error TypeError: Cannot access offset of type Drupal\Core\Extension\Requirement\RequirementSeverity on array in Drush\Commands\core\DrupalCommands->requirements() (line 116 ... src/Commands/core/DrupalCommands.php) is received

To Reproduce

1. Upgrade Drupal to 11.2
2. execute drush rq

System Configuration

Q	A
Drush version?	13.6
Drupal version?	11.2
PHP version	8.4
OS?	Linux

Additional information
Drupal 11.2 is just around the corner
I guess we should fix this until then

I've created fix for myself that supports both constants and enums
I can create PR, once Maintainers give me inputs
