Ability to show/hide navigation items about podman-desktop

[benoitf]

here it's not clear where the state is managed/handle

It's user state but needs to be on disk, so maybe storing a set of the hidden ids in configuration would be easiest?

I wasn't clear, I mean:

• is that the frontend that read the properties and display things
• backend that read the properties and then expose methods and frontend read the data from there

Nav items from extensions are contributed via backend, but I can't think of any reason why the backend would need to know the full list of what we display (e.g. that there is a dashboard or extensions nav item), what's currently hidden, etc., so I would say this is all in frontend.
