[JENKINS-69760] "git lfs install" fails on Windows agents with git plugin v4.12.1

The v4.12.1 git plugin breaks when doing "git lfs install" during a Jenkins job. The attached image shows the error. It also breaks the command on the machine in the repo directory. It works when I delete the repo folder on the machine and rerun the job, but when I re-run it again it will always break.

Error has a weird path "\NUL:\pre-push" and saying that the path is incorrect. Not sure why it cannot go to .git\pre-push.

The issue was never there. I can confirm that having the git plugin on v4.11.5 works really fine.
