Run tests on emulated architectures

[WilliamJamieson]

This is probably a feature request.

I would like to use OpenAstronomy to run tests on some emulated architectures. That is

• s390x
• aarch64

Akin to what astropy does here: https://github.com/astropy/astropy/blob/main/.github/workflows/ci_cron_weekly.yml#L91-L145 or asdf does (for just s390x) here: https://github.com/asdf-format/asdf/blob/154513dc66ccd3ab1ed6113904c1811d3f47b24c/.github/workflows/s390x.yml#L21-L61.

Really, asdf just occasionally copies the astropy updates to this workflow. It would be nice if this workflow was maintained upstream and use the nicer syntax that OpenAstronomy uses.

hey @WilliamJamieson it shouldn't be that hard to add if you want to take a swing at it, I personally wont have time to have a go for a while.

The workflows linked use this for arch emulation: https://github.com/uraimo/run-on-arch-action
