In my experience its rare to hear of sheared hinge pins especially on boot lids. Sounds like they have become seized for some reason. I would suspect new pins would be a Renault only part but it's possible there may be something available as an after-market component.
Getting the old pins out may be the difficult part and may necessiate the use of a hinge pin removal tool.
It may be prudent to contact a body shop who may have the tools and experience.
