⬆️ Bump Go 1.19 + Chi v5 + set `GOAMD64=v3` (#7589)

* ⬆️ Bump Go from 1.14 to 1.19

* 🏗️ Use Go Modules to build container images

* 🎨 Drop GO111MODULE=on since it's the default

* ⚡️ Set GOAMD64=v3 for AVX2, SSE4.2… instructions

See https://github.com/golang/go/wiki/MinimumRequirements#amd64

* 🎨 Rename module name "chi" -> "chi/server"

This change sets the default executable name to "server".
We may also drop the "-o server" in the Dockerfiles.

* ⬆️ Bump Chi from v4.1.2 to v5.0.7
