Reorganize Navigation menu items and make them consistent with other similar pages in core

I'm at DrupalCon Atlanta and am interested in giving it a try! Let's see how far I get. ;-)

Ok, It's updated, and when I test it, the navigation menu items are reordered and match in text case:

Good progress so far! :)

Added a minor comment to the MR to reduce a bit the file footprint. Besides that, would be great if the Navigation settings form page could be updated as well. It is defined in navigation.routing.yml file.

Thank you!

I've changed the case in that page's title to match the link in the menu. Is that the only thing that needed updating?

It looks great!

Marking as RTBC. Thank you!
