[JENKINS-61739] Handle project_rename System Hook event

Hello,

A great addition would be to handle project_rename system hook event.

Currently the behavior is, upon manual scan, the project is duplicated and the old one is displaying as a simple Multibranch pipeline with no way to delete it. I have to delete and re-create the whole GitLab Group, and it triggers all branches for all projects which is very consuming when there's a lot of projects with a lot of branches.
