Migration error when attempting to uninstall

[mmikkel]

Description

Uninstalling CKEditor 5.7.0 is impossible due to a migration error being thrown:

"An error occurred while executing the "craft\ckeditor\migrations\Install migration."

The logs reveal the culprit:

Force-uninstalling via CLI (craft plugin/uninstall ckeditor --force) works.

Steps to reproduce

1. Have CKEditor 5.7.0 installed
2. Navigate to Settings -> Plugins and click Uninstall via CKEditor's disclosure menu
