  # NOTE: It is preferable to list development dependencies in the gemspec due to increased
  #       visibility and discoverability.
  #       However, development dependencies in gemspec will install on
  #       all versions of Ruby that will run in CI.
  #       This gem, and its gemspec runtime dependencies, will install on Ruby down to 2.2.0.
  #       This gem, and its gemspec development dependencies, will install on Ruby down to 2.4.
  #       Thus, dev dependencies in gemspec must have
  #
  #       required_ruby_version ">= 2.4" (or lower)
  #
  #       Development dependencies that require strictly newer Ruby versions should be in a "gemfile",
  #       and preferably a modular one (see gemfiles/modular/*.gemfile).
