I can't find docs in build-push-action that describe the syntax for this - we should probably add that on merging this.

Yes it's a core implementation where you can use --build-arg flag without a value: https://docs.docker.com/engine/reference/commandline/build/#-set-build-time-variables---build-arg
You may also use the
--build-argflag without a value, in which case the value
from the local environment will be propagated into the Docker container being
built:$ export HTTP_PROXY=http://10.20.30.2:1234 $ docker build --build-arg HTTP_PROXY .
