GitHub Action for updating Clojure Events failing

The last event on the [Clojure community events page](https://clojure.org/community/events) is from last October, but there's been quite a few events on the [Zulip events feed](https://clojurians.zulipchat.com/#narrow/channel/262224-events) since then. I suspect this is due to an error in the [publish-events.yml](https://github.com/clojure/clojure-site/blob/4505a8ea296365c0e98e8f23d664792adc91ef7a/.github/workflows/publish-events.yml#L42) GitHub Action. The action checks for the word "modified" in git status, but if only new files are added, this doesn't occur. Instead, may I suggest using `git diff --quiet --cached` to check to see if there's any staged differences after running `git add content/events`. This will return an exit code of 0 only if there are no differences, so we can use the inverse to check to see if there should be an update. ```bash git add content/events if ! git diff --quiet --cached then git commit -m 'update events' git push fi ```
