Determine the Ruby versions for your testing matrix based on the gemspec.
Maintaining your CI is tedious and your gem can already specify the compatible Ruby versions using required_ruby_version. This action reads your gemspec and provides an output of compatible Ruby versions.
A static list of compatible versions is maintained. This is a subset of setup-ruby's supported versions.
