Node.js 16 is deprecated

[player-03]

GitHub is warning that this action needs to be updated to use Node 20. More details: https://github.blog/changelog/2023-09-22-github-actions-transitioning-from-node-16-to-node-20/

I see that action.yml specifies 'node20', but package.json and .node-version still say 16. Perhaps one of those is the problem?

It seems like updating action.yml is what's needed, but this change is not available yet in the v1 tag.

Yep, the latest release is from before the change:

https://github.com/krdlab/setup-haxe/releases/tag/v1.5.1 vs 4c84397

Can we have a new release @krdlab? Not sure if it needs to be v2 to make it a version bump like other Github actions did.
