fix: correct GitHub API path for deleting label-reminder comment (#157)

The DELETE endpoint for issue comments does not include the issue number
in the path (`/repos/{owner}/{repo}/issues/comments/{comment_id}`), unlike
the LIST endpoint which does. The extra `$PR_NUMBER` segment produced a
404, leaving stale reminder comments on PRs after the codebuild label was
added.
