Strict id in cookies_banner_server()

[JT-39]

Describe the bug

In the code for the function cookies_banner_server() there is a strict id value of navlistPanel which the cookies page of the app must belong to in order for the link "View cookie information" to take you to the page.

How to reproduce

This is the section of the cookies_banner_server() code:

    shiny::observeEvent(input$cookies_link, {
      shiny::updateTabsetPanel(session = parent_session, 
        "navlistPanel", selected = cookies_link_panel)
    })

Fix

It would be useful to either have this as a more flexible id value, or document that the main navigation tabset/navset should have the id value navlistPanel.
