Cleanup commit-graph-chain.lock file after crash
SRE is currently having to manually clean up this lock files after crashes.
Based on @jacobvosmaer-gitlab's suggestion in https://gitlab.com/gitlab-org/gitaly/-/issues/2685#note_327987321, this adds the lock file to the ones gitaly cleans up automatically.
This currently runs 15 minutes after the lock file was created.
