Add the Analysis Facilities White Paper source to https://github.com/HSF/documents

See the discussion at #1722 (comment).

Indeed the paper (https://arxiv.org/abs/2404.02100) is tagged originally as HSF-TN-2024-01 but does not appear at https://github.com/HSF/documents/tree/master/HSF-TN.

Ping @nskidmor.

Hi @lukasheinrich, can you provide the HSF with the source of the white paper, please? This is something we do by default. Thanks a lot.

Thank you @nskidmor for stepping in. I created HSF/documents#150 to add the sources to the repo.
