Missing hidden depedency on edit_plus

Thank you Lucas! There's actually a bunch of technical debt around this one. Not totally sure what to do about in the meantime tbh.

Edit+ is a tool plugin for Toolbar+. So I think the info files are correct in that edit+ depends on toolbar+, but yeah there is definitely a hidden dependency. Would the two modules depending on each other cause a circular dependency? I've ran into that before, but not sure how I got there.

Edit+ and Layout Builder share a tempstore for hanging onto changes before the entity is saved. Because of the order that the modules were developed the tempstore handling is in Edit+ at the moment, but it should really be bubbled up to toolbar+.

There are still some sea change tasks coming up where this will be addressed.

Also, this module is probably going to be moved to navigation_plus since we started using navigation when it came out.
