[Tor www-team] TPA RFC 30: Changing how lektor plugins are used

Hi all, A while ago lavamind suggested we change how our lektor sites consume and symlink plugins from lego. It was related to another RFC I wrote, so I've also written TPA-RFC-30. You can find the TPA-RFC at this link <https://gitlab.torproject.org/tpo/tpa/team/-/wikis/policy/tpa-rfc-30-change-lego-plugins> and the discussion thread is <https://gitlab.torproject.org/tpo/web/team/-/issues/16>. I'd appreciate your input if you have any! Kez
