Add go licenses to licenses.txt (#21034)

`make go-licenses` will generate `assets/go-licenses.json` which is then included in the webpack build. 

This step depends on both go and node being present, so unfortunately, I could not automate the generation by hooking it up to `tidy` as that target is triggered on CI where we do not have a docker image with both go an node.

It should be ran from time to time, ideally after each go mod update.
