While the xtask code base is better engineered than our slightly messy Nox
manifest, all functionality is available via Nox including some that is not
available via xtask. Finally, only the Nox sessions are used in the CI by now so
that xtask does not see regular automated usage.
2869: change latest URL from netlify proxy to redirect r=davidhewitt a=davidhewitt

Closes#2867
