Still able to access admin settings pages with allowAdminChanges => false

[rjgux]

Description

I'm not sure whether this should be labelled request or a bug. With 'allowAdminChanges' set to false I can still access admin settings pages in the CMS e.g. /admin/settings/sections or /admin/settings/sections/new which is confusing.

Links to these pages are hidden in the sidebar, but can still access them via a URL. I'm not able to save these admin pages (throws the NotSupportedException - Changes to the project config are not possible while in read-only mode), but I wouldn't expect to see any page in the CMS where you can effect the config, before actually saving.

Steps to reproduce

1. Open CMS admin
2. Navigate to an admin settings page via a URL
