Add logging option

[mattrosno]

I'm struggling to figure out why this is only working on ~7 of my 26 open pull requests. Would it be possible to add logging so as I watch the workflow run I can see what's happening?

For context, I'm trying to add a label squad: system to all open PRs and then package: foo labels based on package directory in our monorepo.

Any suggestions on how to best debug this?

Sure. Added logging in dffbc90, hope it helps :)
