To change to GitHub CI involves more than changing the .gitlab-ci.yml to the github equivalent.

There's a bunch of permissions to enable on GitHub.

This includes both the secret permissions here, as well as permission for this repo to access the container image on github otherwise github won't be able to run it.

I think in the future @brynblack you should be automating the github access across all the repos using pulumi in the orchestrator. There's too many to be manually setting up all the time.

This is a good example to follow to apply to other library repositories @tegefaulkes @brynblack.
