Upgrade to Go 1.20

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.

3. I tried with go 1.20, in the current nixpkgs checkout.

   This time, it looks like it's not complaining about a missing -p flag, but it's unable to find imports from stdlib (for example in //tvix/boot:tvix-init`):
