Upgrade to Go 1.19

Opened by sterni at 2022-10-31T13·56+00

Current nixpkgs defaults to Go 1.19, we need to stay with Go 1.18 for some parts of depot:

Go 1.19 changed formatting, so we need to reformat Go code in depot
//nix/buildGo doesn't work with Go 1.19, error message seems to be complaining about a missing -p flag, but I did not investigate more.
