 As part of the audit on possibly flooded OpenPGP keys (#31168), we noticed
 that the old website suggests users fetch keys from keyserver. This is a
 problem right now because the keyserver has poisoned keys for TBB, among
 other things.

 During a discussion on the topic, weasel suggest we unindex the archived
 website (2019.torproject.org) from search engine so that people stop
 referencing it. We should also make sure this specific page is not linked
 anywhere in our live documentation, if possible:

 https://2019.www.torproject.org/docs/signing-keys.html.en

 This could be accomplished by a `X-Robots-Tag: noindex` header, or by
 dropping a robots.txt file in the root of the site.

 Thanks,
