Currently we use a forked version of a (no longer maintained) release github action which still uses set-output:
https://github.com/firebase/firebase-admin-python/blob/master/.github/workflows/release.yml#L110

Would we want to consider moving this to a new maintained source like https://github.com/ncipollo/release-action?

Thanks! LGTM!

good call! I think we should. Let's do it in a separate PR though. Is there an official github action for this now?

The original repo the fork was based on was the official one until they stopped maintaining it in 2021.

They left suggested alternatives with the one i linked being the most active but the thread of mentions shows a few repos who decided to use https://github.com/softprops/action-gh-release instead.
