rankett.net v5.1.0 upgrade: upcoming maintenance

rankett.net will go offline for maintenance starting on Friday, May 19, 2023 starting at 2:00PM EDT. The downtime will hopefully take less than an hour.

This maintenance will be to upgrade rankett.net to Peertube version 5.1.0. After rankett.net is brought back online, user registration approvals will be enabled.
