f09986aa - [clang-format] Use proper flags for git diff-tree (#155247)

[clang-format] Use proper flags for git diff-tree (#155247) From local testing, git diff-tree does not support three dot diffs correctly, instead expecting the --merge-base flag to be passed along with two commits. From my reading, the documentation (https://git-scm.com/docs/git-diff-tree) also confirms this. This patch updates the git-clang-format script to be correct. I don't think we ever ran into this issue before because we never ended up using it. For the PR code format job I believe we would just explicitly pass the merge base, completely bypassing the problem.
