OwlBot reverts the lint fix

[suztomo]

OwlBot reverted the lint fix (#863) in the commit below (right after I merged 863), and now lint is failing in main (So this PR 861 is irrelevant to the lint failure). The lint is not a required check.

Probably the discrepancy in the google-java-format versions between OwlBot's and this repository's.

OwlBot uses google-java-format 1.7 (a bit old)
