entity.config_pages.edit_form is never used

Problem/Motivation

It seems both entity.config_pages.edit_form and config_pages.add_form declare the same path pattern.
The result is that config_pages.add_form is always loaded and entity.config_pages.edit_form ca never be reached.

Steps to reproduce

Proposed resolution

Either use a different path entity.config_pages.edit_form or maybe just remove it?

Remaining tasks

User interface changes

API changes

Data model changes
