Add support for comma-separated workspace values in repository configuration

[jan-vcapgemini]

Feature idea

As an IDEasy repository user I want to use comma-separated workspace values in my repository configuration, allowing repositories to be cloned into multiple workspaces during project setup.
So I don't have to use the workaround by simply having duplicate repositories configurations with different names pointing to different workspaces. This proposed feature is for convenience only.
