[workflow] Add workflow to automatically bump the s390x runner version

[chantra]

Get the last release from GH API and update the relevant line in the Dockerfile

[chantra]

Tested by merging in chantra/runner in chantra@53b9814

Started the workflow manually (workflow_dispatch event) on main branch
https://github.com/chantra/runner/actions/runs/3952462711
which generated chantra@9cdba02

I suppose that approach-wise this is probably fine, but I am a little hesitant about having some workflow just bump a version without anybody noticing. Not that it is necessarily much different right now, but it's also not great right now :-)
Is there a way for us to create a pull request instead? (Edit: I inferred that the action in question just pushes; if it already creates a pull request then that's fine, but that was not my reading of the docs)

[danielocfb]

Also, just curious, but have you tested what happens when the version stays the same? Does the action just not create a commit and do nothing?

that's what the action documentation says, yes. https://github.com/marketplace/actions/git-auto-commit

yes, currently, at least for the non s390x, upstream eventualy update the version and it trickles down to us.
I don't think the current action I am using can create a PR, but maybe another one, I would have to search for it.

Ok, I found peter-evans/create-pull-request@v4 which is similar and just create PRs.

Tested on my repo.

PR created: chantra#15
actual run:
https://github.com/chantra/runner/actions/runs/4011625579

[chantra]

I am less sure if the team-reviewers feature will work or not, let see if on next run that creates a PR.

Looks good, thanks!

Typo; should this sentence have to be updated?

[chantra]

done.
