[JENKINS-68991] Controller path altered in mixed OS environment

We have an issue when running pipelines in a mixed environment with a Linux controller and Windows agents.

When using a pipeline job that uses either the node or label parameters, if the node defined by the param value is a windows node then the pipeline checkout stage fails.

The path of the controller is perfectly fine and any pipeline that doesn't use the node or label parameter types is correctly checked out from the same scm system with the same credentials.

It appears that the path on the controller is being overwritten by the path of the node resolved by the param.

When we change the label param to a simple string param and resolve the nodes explicitly in the pipeline everything works correctly.

Its not clear is this is an issue in the node and label parameter plugin or the gitscm plugin or a combination of both.

Start by reproducing the pipeline checkout stage with a node or label parameter on a Linux controller and Windows agent. Trace how the resolved node affects the controller path and the GitSCM checkout, considering the nodelabelparameter and git-client components. Done means the checkout preserves the controller path and succeeds with credentials in the mixed-OS setup, with a regression test if the relevant test entry point is identified.
