Fix Windows CI failure in ExplainJsonCliOutputIT by removing inner quotes from -e args

Java ProcessBuilder escapes internal " with \" but cmd.exe doesn't recognize
\" as an escape - it treats every " as a quote toggle. This caused the SQL
argument to be split into broken tokens with extra \ chars, producing
malformed SQL that the server couldn't parse.
