ruby/setup-ruby provides everything that this action has provided.
But it's not true.
With rbenv I can switch versions on-the-flight, for example gem generator supports only Ruby >= 3, but the gem template supports >= 2.6.
So, how can I do this with ruby/setup-ruby? Nohow, I think.
But with matrix like 2.6, 2.7, ... I can use the base Ruby versions for the template testing, and rbenv install 3.0 && rbenv local 3.0 for generation in pre-steps.
I see the warning:
