Show association with an Eclipse project on the accounts page also for contributors
Triggered by eclipsefdn/helpdesk#2700 (moved), I noticed that association with an Eclipse project on the accounts page is only shown for committers and project leads, but not for contributors.
Random example: user https://accounts.eclipse.org/users/hzierer is a contributor (defined in PMI) for Tractus-X, but in the projects tab a message says: "This user is not involved in any Eclipse Projects."
