"merged notification" workflow is being skipped

[zeke]

We've had a few PRs land on this repo, but it appears none of them are getting comments after being merged to main.

https://github.com/github/docs/actions?query=workflow%3A.github%2Fworkflows%2Fmerged-notification.yml

I think this may be because of the conditional?

if: github.event.repository.private == false && github.event.pull_request.merged && github.event.pull_request.base.ref == github.event.repository.default_branch

@zeke now that the repo is public, these workflows are running but failing! I opened #183 to get that fixed.
