After this PR, https://github.com/ethereum/go-ethereum/pull/28187, the way to set the default logger is different. This PR only updates the way to set logger in some test cases' comments that existed in the codebase (since this commit https://github.com/ethereum/go-ethereum/commit/b63e3c37a6). Although I am not sure if it a good way to leave the code in the comment, it truly makes me more efficiently to debug and fix the failing test cases.
