Don't delete empty blocks on Enter
Created in the Ketida repo in: https://gitlab.coko.foundation/ketida/ketida/-/issues/561
Context
In the book editor, if I click on an element in the left, for example Key questions, it creates a Key questions section. Then if I hit Enter to get out of the Key questions block, the section is removed if I didn’t already add content. As a user I want to leave the section blank for now and come back to it. The user can always backspace to intentionally remove the section.

Proposal
Don’t delete empty blocks on enter. The way to delete an empty section or block will be to backspace to intentionally remove the section.
