Improve error message when an editor tries to delete a chapter that is locked by another editor
Context
When a user with edit access tries to delete a chapter locked by someone else, selecting the “Delete” button shows a warning modal with text “Unauthorized action You don't have permissions to perform this action. Please contact book's owner”
This behaviour is correct but the error messaging is not sufficiently explanatory.
Proposal
Improve error message to:
You can’t delete a chapter that is currently being edited by another book member with edit access.
