Fix automated docker builds
The docker builds (https://cloud.docker.com/repository/docker/bilbydev/bilby-test-suite-python37) seem to be taking a long time to complete/failing. This could be a dockerhub issue so I'll wait to see.
Maintenance will be performed on git.ligo.org, containers.ligo.org, and docs.ligo.org on Tuesday 23 April 2024 starting at approximately 9am PDT. It is expected to take around twenty minutes and there will be several periods of downtime throughout the maintenance. Please address any comments, concerns, or questions to the helpdesk.
