📝 Provide a description of requested docs changes

What is the purpose and what should be changed?
I recently worked on a legacy application which migrated to CKEditor 5 from 4. The system had content that had script in it. This resulted in the editor crashing out. It would be great if the docs pointed out that by just adding the script to the allow list the issue would be solved. I have a draft PR setup for this change already. I will publish that along with this issue. Please check
