Update all dependencies

This takes part of the work being done in #96 that was reverted but still useful.

Note Tailwind and Fresh weren't upgraded because there's no security vulnerability in either, and I have found the new versions to be worse in performance. Thos will likely stay at those fixed versions going forward.
