사용하지 않는 코드는 삭제

https://github.com/kimchaeminthegreat/Node.js_Level1_Task/blob/79343d10af1054ad8adfbda8105731dcbdd555d0/routes/comments.js#L14-L15

이런 코드들 다 삭제해주세요~ 하나하나 방치하다보면 코드가 관리가 안됩니다~

Start with routes/comments.js at lines 14-15 and inspect the surrounding route code to confirm what is unused. Search the repository for similar unused code, then remove only the identified dead code; done means the cleanup is complete without changing active behavior.
