Clickable links for namespace segments

[ceedubs]

For example if I am currently viewing the public.base.latest.Either namespace, it feels like I should be able to click on the base segment of the path to change my perspective to unison.base.

If this were to be added, it may be reasonable to remove the arrow that goes up one level, because it would be just as easy to click on the parent segment.

I think this is a natural and probably expected interaction to add.
The challenge is with the cropped part, but maybe its fine to say you can only click up and to base in the above example and if you want further up you can click on the following screen.

We might also add a "jump to" interaction 🤔

@hojberg I think that would be fine for now and still an improvement.

Done :)
