Missing Single Directory Component (sdc) dependency

Problem/Motivation

When you try to enable this module without Drupal core's sdc module enabled, the following error message occures:

The service "Drupal\cl_editorial\NoThemeComponentManager" has a dependency on a non-existent service "plugin.manager.sdc".

Steps to reproduce

• Spin up a fresh Drupal installation
• composer require drupal/cl_editorial
• Enable cl_editorial module (e.g. via drush en cl_editorial)
• See the error message

Proposed resolution

• Either do not use the plugin.manager.sdc service or add drupal:sdc to module dependencies

Remaining tasks

• Create an issue fork and merge request to fix this issue
