Node 16 is deprecated on GitHub, use Node 20

@eregon #540, other actions increased their major version for this change. e.g. https://github.com/actions/checkout/releases/tag/v4.0.0

Yeah I know. IMO that's unnecessary work, it's making everyone change things when nothing needs to change in their workflow actually, at least as long as they are running on GitHub-hosted runners. And if not, then node20 should be installed on self-hosted runners. So anyway, nothing meaningful to change for workflows, so a waste of a major version.

That's a node package, embedded into dist. I don't think GHA can see that.

Are you sure there's no actions/cache@v3 in your workflow or one of the composite actions?

Could you make a PR? You just need to change https://github.com/ruby/setup-ruby/blob/master/action.yml

Note: the warning won't show for now: actions/upload-artifact#444 (comment), but a released version should be ready for when they bring it back.

👋 I'm still seeing warnings about upgrading to Node 20:

I believe this is due to this action's use of actions/cache@v3:

setup-ruby/package.json

Line 25 in 22fdc77

"@actions/cache": "^3",

Version 4 for actions/cache doesn't appear to actually have breaking changes. Would it be possible for this action to bump to v4 of actions/cache?

@TWiStErRob I found v3 of action/cache in another 3rd party composite action that I missed the first time through trying to find the source of the warning I was seeing. Thanks for taking the time to respond.
