workflows: add triage-ci.yml

[carlocab]

This will allow us to add automation that will be done after CI
failures.

For now, we can automate pinging @woodruffw and @alex on failures of
the brew-pip-audit workflow to avoid other maintainers from having to
manually do this.

Could this be done in that workflow instead?

I think that's phrased in a confusing way: brew-pip-audit generates regular PRs to bump resources in formulas, we're interested in CI failures on those PRs, not failures in brew-pip-audit itself.

Yes, exactly, sorry for the lack of clarity.

Given the desired behaviour the workflow needs to live here. I can stick this into an existing workflow (e.g. automerge.yml), but I imagine we'd rather have shorter workflows that do specific things rather than fewer but longer workflows that do multiple different things.

Ok, thanks: with that context this approach makes sense to me!

[woodruffw]

LGTM, thank you @carlocab!
