Publish reduced orso files as part of nightly builds

[nvaytet]

Fixes #123

[jl-wynen]

Do you have a solution for accessing the artefact now?

[nvaytet]

I think the solution is to create a github account and use github cli, unless you can think of another place where we can publish the artifacts (somewhere else on github?)

[jl-wynen]

Let me rephrase, do you / we have a tested solution that we know works?

[MridulS]

Just to unblock @mEngstroem while he is writing the integration test I have started a cron job in a server that fetchs the newest run and uploads the reduced data to https://pub-6c25ef91903d4301a3338bd53b370098.r2.dev/amor_reduced_iofq.ort
We can change the URL downstream while we test things out.

@MridulS in this PR, we will make both latest and stable artifacts.
Is your service able to fetch both and post them both?

Also, there may be more files in the future, not just a single file.
Would probably be better to publish a zip archive?

[MridulS]

The current service fetches only from nightly_at_main workflow, but yes it can fetch and upload from multiple runs. The bash file running is available here https://gist.github.com/MridulS/79d7de68b27276da6fafa4f6c7bc9645
