deleteHook fix not available from NPM

While using the package installed from NPM, i notice that deleteHook had an error where "/repos/" was not prepended to the path. I subsequently noticed that there was a fix for this on January 30, 2017 here: https://github.com/github-tools/github/pull/418

Unfortunately, this fix does not seem to be included in any of the releases. When I install from npm, i still see the version with the bug. Would it be possible to roll this into a new release and published?

Thanks for your time

先檢查 pull request #418 和 package 的 NPM 發行流程，以確認為什麼已發行的版本中缺少 deleteHook 修正。驗證已發行的 package 包含修正後的路徑行為，然後發行一個新版本，並確認已安裝的 NPM package 包含該修正。
