rubocop-1.61.0 crashes when the project's gemspec dynamically sets spec.required_ruby_version

[postmodern]

If a ruby project's .gemspec file dynamically sets the required_ruby_version value, this causes rubocop to crash while attempting to parse the right-hand side of the spec.required_ruby_version assignment.

Expected behavior

rubocop does not raise an exception.

Actual behavior

Exception during parsing of the .gemspec file.
