Subject: [PATCH] Fix COMMIT_ID in regression_test.sh (#9047)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Summary:
https://github.com/facebook/rocksdb/issues/8031 broke internal tests. This should fix but also preserve
the intended capability of getting git commit id when hg not used

Pull Request resolved: https://github.com/facebook/rocksdb/pull/9047

Test Plan: already broken ¯\\_(ツ)_/¯
