[JENKINS-33126] unstash fails to overwrite read-only files

We're using stash & unstash to pass a checked out git repository between steps in our workflow.

On first run the unstash works successfully, however on a second run the unstash fails because some of the files in the `.git` directory are read-only.

I've attached the stack trace, it's a bit misleading, we've fixed it by running a `sh 'chmod -R u+w .git'` before the unstash step.
