Work is being done to allow installation of current Rubies for 2.3 thru 2.7, along with JRuby & TruffleRuby. The work is community supported, no word from GitHub yet...
That's what I was referring to. Speaking of rvm, and being a Windows type, does rvm do anything with cert files? Windows installs ship with one, but not sure how they're handled on Ubuntu & macOS...
I think it would be useful to link to a list of supported Ruby versions from the README though.
That data is really hard to find for people which don't know a lot of details about GitHub Actions.

Taken from actions/runner-images#281 it would be great to at least make very clear that actions/setup-ruby is not able to install versions of Ruby, just setup predefined ones.
IMO there does not need to be a list in this repository, a reference to the currently available versions would be sufficient.

How one can find out which versions of Ruby are available?
