[BUG] - JupyterHub navbar items not redirecting correctly after visiting Admin Dashboard

[marcelovilla]

Describe the bug

Nebari borrows some navbar items from JupyterHub, such as the Home, Token and Admin tabs. These work fine until one goes to the Admin tab. After visiting the Admin Dashboard, trying to go back to any of the Home, Token, and even the Admin tabs result in a 404 page not found error. Here is an example of the Token tab, before and after visiting the Admin Dashboard:

As you can see, the Token tab URL is /hub/token before visiting the Admin Dashboard, but becomes /token after that.

I can reproduce this behavior (i.e. URLs changing after visiting the Admin Dashboard; see lower left corner in the video) locally using vanilla JupyterHub, with the difference that redirection works fine:

I guess we can have Nebari redirect /token to /hub/token but we would need to make sure that's not a general rule, as other services don't have the /hub prefix. For example: /conda-store.

Expected behavior

I would expect for users to be able to go to the Admin Dashboard and then navigate back successfully to other sections of JupyterHub (e.g., the Home or Token tabs).
