What Operating System are you using (both controller, and any agents involved in the problem)?

Ubuntu 22.04.4 LTS (GNU/Linux 5.15.0-94-generic x86_64)

Reproduction steps

1. Enable "Enable authentication for '/project' end-point" of Gitlab plugin in Jenkins.
2. Create a multibranch project in Jenkins.
3. Create a Branch Source targeting a gitlab project.
4. Configure a Webhook in Gitlab targeting "https://#jenkins#/project/#project# for push events (all branches).
5. Test the webhook with a push event.

Expected Results

HTTP 200 response code is received.

Actual Results

Hook executed successfully but returned HTTP 403
