Replace Jekyll

It works, but dealing with Ruby is kind of a pain (and Nokogiri security vulnerabilities are kind of annoying too)

Likely replacing with https://github.com/getzola/zola

Need to figure out how:

• how to migrate my pages and posts
• keep URLs working
• migrate my theme

Switched theme to terminiminal for simplicity, but otherwise done.
