git-bisect-lk2009: update nist report link

Commit d656218a83 (docs/bisect-lk2009: update nist report link,
2017-04-20) replaced a dead link to news release on nist.gov.  However,
this might be confusing to the reader (like myself) because the article
git-bisect-lk2009.txt quotes from the news release but the exact quote
cannot be found in the full report.  In addition to that, the link added
in 2017 is also dead in 2023.

Replace the reference to nist.gov with an version of the original NIST
news release archived to the Wayback Machine.  Include also an updated
link to a live version of the full report.
