Merge branch 'archived_project_badge' into 'master'

Add archived badge to project listing

## What does this MR do?

Add an `archived` badge to the user project list, if the project is archived. 

## Are there points in the code the reviewer needs to double check?

No.

## Why was this MR needed?

Customer noted in https://gitlab.zendesk.com/agent/tickets/33787 that there is no distinction for archived projects in the project dashboard/explore projects page. There is an archived badge on the admin projects page, though.

## What are the relevant issue numbers?

## Screenshots (if relevant)

Existing admin projects page:
