node-test-commit-arm-fanned failing

The issue is a Jenkins CI failure on the 'node-test-commit-arm-fanned' job due to a git lock file conflict. Start by examining the Jenkins job configuration and logs linked in the issue. Check for concurrent git processes or stale lock files on the build agent. Understanding Jenkins pipeline and git operations on the specific Ubuntu runner is needed to diagnose and clean up the state.

Builds on test-mnx-ubuntu2204-x64-1 from (and including) https://ci.nodejs.org/job/node-test-commit-arm-fanned/50177/console are failing:
