Use GitHub Workflow for CI

@takluyver Tests 'work' as in they actually run properly, but some are failing, any idea why?

One nice thing that Circle CI offers, and as far as I know no other CI service does, is that when a job fails, you can re-run it with an SSH server enabled, then SSH in to investigate interactively. This has been useful on occasion with testing the GUI - if something hangs, you can SSH with X forwarding, run in the exact same environment, and see what's happening.

I haven't used this very often, so maybe the benefits of Github actions outweigh it, but it's worth noting that there's some downside here. You might want to see what @CammilleCC thinks, as the person now mostly responsible for the GUI code.

There is an action for this: https://github.com/marketplace/actions/debugging-with-ssh

Which can use the public SSH keys you have added to your GitHub profile to let you access the CI as it runs.

TBH I think that it should be simple to reproduce the CI environments locally, at the top of the CI log you can see the information about the environment setup:

 Current runner version: '2.289.2'
Operating System
  Ubuntu
  20.04.4
  LTS
Virtual Environment
  Environment: ubuntu-20.04
  Version: 20220405.4
  Included Software: https://github.com/actions/virtual-environments/blob/ubuntu20/20220405.4/images/linux/Ubuntu2004-Readme.md
  Image Release: https://github.com/actions/virtual-environments/releases/tag/ubuntu20%2F20220405.4
Virtual Environment Provisioner
  1.0.0.0-main-20220325-1

And there's the the act tool to run the CI locally: https://github.com/nektos/act

act is pretty neat, it's extremely useful, you can run the CI pipeline triggered by a certain event (e.g. pull_request, push, merge, whatever), or you can run a specific job (test) locally
