Add Navigation module compatibility

Toolbar is a core feature.

Navigation bar is a Core Module and is default in v11 as I know. It is experimental in 10.3, but honestly it works sooo great - there is no need wait and not using it. This is a massive usability step forward - i install it on every site. No issues yet except Workbench.

Still marked as experimental in 11.x

I'd be happy to review an MR though.

I will also note that I reviewed the module and it has no API and no clear means for adding items.

I would wait until it is stable and those are provided, as they are in Toolbar now.

From my understanding this is just core menu api. Add the menu items and routes and we are done… not that complicated.
