Show indicator for projects created and owned by banned users

What does this MR do and why?

Partially resolves https://gitlab.com/gitlab-org/modelops/anti-abuse/team-tasks/-/work_items/397

Display hidden resource icon instead of visibility level icon for projects created and owned by banned users. Since these projects are hidden, the indicator will only show for admin users.

How to set up and validate locally

Note: In the URLs below, replace (username) with the username of the user in (2), (project-slug) with the project slug created in (3), and group-slug with the group slug created in (4)

Example: group slug

1. Enable the feature flag

   $ rails c
   > Feature.enable(:hide_projects_of_banned_users)
   => true

2. Create a non-admin user or use an existing one
3. Create a personal public project (under the user namespace not a group)
4. Create a public group then create a public project under that group
5. Login with an admin account (root)
6. Go to http://localhost:3000/admin/users/(username). Ban the user.
7. Go to http://localhost:3000/ and search for your project. Validate that the correct icon with a tooltip is displayed (see screenshots above).
8. Go to the project page: http://localhost:3000/(username)/(project-slug). Validate that the correct icon with a tooltip is displayed (see screenshots above).
9. Go to the admin project page: http://localhost:3000/admin/projects/(username)/(project-slug). Validate that the correct icon with a tooltip is displayed (see screenshots above).
10. Go to the group settings projects page for the project created in (4): http://localhost:3000/groups/(group-slug)/-/projects. Validate that the correct icon with a tooltip is displayed (see screenshots above).
