RFR: 8335654: Remove stale hyperlink in divnode.cpp

Thu Jul 4 03:30:47 UTC 2024

This is a trivial patch to remove a stale hyperlink in divnode.cpp. I noticed while reading the code that this link no longer points to the relevant Hacker's Delight code, and since the referenced code ([archived version](https://web.archive.org/web/20070507103558/http://www.hackersdelight.org/HDcode/mulhs.c)) is also embedded in the comment, let's remove it.

Thanks!
