Enhancement request

Some statuses aren't supported (it says xx Status Code xx) instead of status code meaning (xx gets replaced by number)

---

Problem it solves

I made https://evalbot.vercel.app/api/status and I use https://http.dog to validate statuses

---

Additional information, screenshots, or code examples

I like cats more but I use this instead of https://http.cat because it has more statuses and json support

From what I could see, the HTTP reason phrases displayed by httpie come directly from the requests package (specifically here) so that's where you should make a PR to add them.
