* Remove makefile (it's not used anymore)
* Directly download and install nodejs package
The Packages file for deb.nodesource.com/node_16.x doesn't list older
versions, so only the most recent version of nodejs is available. We
don't want to require every update to the build container to have to
update nodejs if a never version is available, so I manually download
the deb and install it with dpkg.
* Update Go version
* Update lib.star
* Generate new .drone.yml
