LogicException: The hook update_dependencies on class Drupal\webform\Hook\WebformInstallUpdateHooks does not support attributes and must remain procedural

Problem/Motivation

Look at the test run results made on next minor Drupal core.

Proposed resolution

As current documentation says, keep the hook procedural.
