Move Catalog about panel to the header

What does this MR do and why?

IMPORTANT This MR requires production to be running gitlab-ui 66.13.0 to have access to the new CSS based skeleton loader. It seems that !131146 (merged) is blocking future updates so I have added it as a dependency.

We are moving the "About this project" sidebar to instead be under the project description horizontally:

#415657[Details-inputs-table-v2.png]

How to set up and validate locally

1. Make sure you have an premium license for your GDK
2. Login as an admin user
3. Create a few projects that you will be able to convert to Ci resources. Create them under the admin namespace for ease of testing.
4. Once you have done so, get the ID of the first new project you wanted to convert. Then in Rails console, run:

projects = Project.where("id > ?", your_first_project_id)
projects.each do |project|
  project.update!(description: 'description')  
  ::Ci::Catalog::Resource.new(project_id: project.id).save   
end  

1. Navigate to /$namespace/$project/-/ci/catalog/resources/. Any project under the same namespace will do (in this case, anything under the admin namespace)
2. Click on a resource
3. Notice the new layout!
