Subject: [PATCH] docker ci: aggressive runner disk reclaim before image builds

A staging run of the studio image build died with ENOSPC during the
Studio venv install: the hosted runners' default free space does not
fit the base image plus buildkit state plus the Studio layer. Drop all
unused preinstalled toolchains and the runner's preloaded docker
images in both build jobs.
