'@requires module' test annotation is deprecated

[github-actions]

https://www.drupal.org/node/3418480

Introduced in branch/version: 10.3.x / 10.3.0

@requires module x is not a supported syntax in PHPUnit 10, and its parser no longer processes it. In the past, Drupal used this annotation to ensure a module was available in kernel tests:

  * @requires module mymodule

This has not been working since PHPUnit 7 was adopted. That made TestCase::checkRequirements a private method of the base class, making Drupal\Tests\TestRequirementsTrait::checkRequirements never be called again.

The annotation and Drupal\Tests\TestRequirementsTrait::checkRequirements are now deprecated for removal in Drupal 11.
