Incorrect installed plugins version key in settings.yml

Problem/Motivation

Under the "Harder" and "Hardest" section of the CKEditor Media Embed Plugin project page → , step 4 says:

4. Run drush config-set ckeditor_media_embed.settings plugins_version_installed [INSTALLED VERSION OF PLUGINS]

But this setting is incorrect. It should be plugins_installed_version as can be seen in config/install/ckeditor_media_embed.settings.yml.

Proposed resolution

Change step 4 for "Harder" and "Hardest" on the project page to say:

4. Run drush config-set ckeditor_media_embed.settings plugins_installed_version [INSTALLED VERSION OF PLUGINS]

FWIW I didn't follow those steps exactly since I installed it with composer following the approach noted in this issue comment → . I guess that's the unspeakably hardest level, LOL, but I expect it's a pretty common use case.
