I found this repo extremely useful and wanted to use it with the latest crate versions.

Crates updated:

• axum 0.4 -> 0.7.3
• hyper 0.14 -> 1.1.0
• config 0.12 -> 0.13.4
• tracing-log 0.1 -> 0.2.0

Hi, I just saw this PR. It looks good, I'll test it and merge if everything works. I'm glad that this repo helped you.

Hey, sorry for the delay, I had exams in February and March. I have a few questions regarding the changes.

1. Since hyper removed the server from its 1.0 release, do you believe it is prudent to use the axum provided server? The axum team made it quite clear that the server is not designed for production use (iirc), and since this is supposed to be as close to production as possible, I think it would be better to wait for the promised server in hyper-extras (? not sure if that's what it's called).
2. I'm not sure if I missed some developments regarding time/chrono. Has chrono been fixed? Or has time fallen into disuse?
3. Should I create a new branch on the repo and restart from scratch with new library versions? It is, after all, an educational repo, and it seems less than desirable to update everything in an older codebase if people are supposed to follow it chapter-by-chapter from the book. Do you agree?
