Update how to contribute

Remove forking from webpage

Description

Since the UNICADO project is currently hosted only on RWTH infrastructure and not on a public platform like GitLab/GitHub, contributors won’t be able to fork it in the usual way. You’ll need to update the How to Contribute section to reflect a different contribution workflow — likely based on cloning, creating a branch, and pushing via direct access (if permitted).
