# Checks that `RUBY_VERSION` constant is not used in gemspec.
# Using `RUBY_VERSION` is dangerous because value of the
# constant is determined by `rake release`.
# It's possible to have dependency based on ruby version used
# to execute `rake release` and not user's ruby version.
#
# @example
#
# # bad
# Gem::Specification.new do |spec|
# if RUBY_VERSION >= '2.5'
# spec.add_runtime_dependency 'gem_a'
# else
# spec.add_runtime_dependency 'gem_b'
# end
# end
#
# # good
# Gem::Specification.new do |spec|
# spec.add_runtime_dependency 'gem_a'
# end
