Allow admins to define pre-pinned resources using a form driven experience

Description

As an admin, I want to be able to use the existing form-driven experience to define the default pre-pinned resources.

Acceptance Criteria

1. Add the `Pre-pinned navigation items` section under the `Developer` tab in the Customization form for setting the default pre-pinned resources
2. Use the DualListSelector component. The list on the left should show the list of all the resources that can be added to the developer perspective navigation and the list on the right should have the resource(s) that the admin wants to show to all new users by default if the navigation is not customized
3. Hide the Developer tab when the Developer perspective is disabled
4. The console configuration CR should be updated as per the selected resource(s)
5. Add intro text to provide a bit more discoverability in the following areas:
   1. Pre-pinned navigation items
   2. Add page
   3. Developer catalog
