Runners paused to due to low disk space

List of failures on 11 October 22:

https://grafana.gitlab.haskell.org/d/167r9v6nk/ci-spurious-failures?orgId=2&from=1665435600000&to=1665521999000&var-types=no_space

I disabled Runners #538 and #535 since the number of failures due to insufficient disk space had gotten too high. They both run on maurer; names are maurer.smart-cactus.org_maurer_d00737ce095c and maurer.smart-cactus.org-lint_maurer_b713ea5d264a. I don't have access to this machine.
