CI is currently broken on git diff: Not a git repository

[viirya]

Describe the bug

A few Github Actions jobs which run git diff --exit-code received a error currently:

warning: Not a git repository. Use --no-index to compare two paths outside a working tree
usage: git diff --no-index [<options>] <path> <path>

e.g. https://github.com/apache/arrow-datafusion/actions/runs/4093544289/jobs/7059343655, https://github.com/apache/arrow-datafusion/actions/runs/4092342002/jobs/7057053547

Found some similar issues like actions/checkout#363, but it was reported long time ago, not sure why suddenly this happens to datafusion CI.

To Reproduce

See action links.

Expected behavior

CI should work.
