[OS] Run jobs on GitHub actions

[ryscheng]

Describe the feature you'd like to request

Would love for our data fetching scripts to run on the regular in GitHub Actions CI.

Describe the solution you'd like

This includes:

• Refactoring our scripts to be idempotent
• Setting up a standard environment (either in Docker or actions config)
• Setting up a new GitHub actions environment for secrets

Describe alternatives you've considered

This PR sets up os-observer to run in GitHub actions via a CLI interface.
Currently manually triggered.

This adds os-observer to the monorepo and turbo builds

I'm going to close this out, since we can trigger os-observer manually from GitHub actions here:
https://github.com/hypercerts-org/hypercerts/actions/workflows/os-observer.yml

See here for an example run:
https://github.com/hypercerts-org/hypercerts/actions/runs/5106660306/jobs/9178986925

It'd be a trivial change at this point to make it run on a schedule

I'm going to close out this issue and open this issue for the remaining script rewriting work:
