Hello there!

I'm one of the maintainers for @DataDog's ddtrace gem. We still support customers running Ruby 2.0, and run our CI with Ruby 2.0 as well.

We've noticed that the latest 3.2.5 release no longer works on Ruby 2.0. Of course, it doesn't make any sense to ask upstream to still support Ruby 2.0 (good riddance), but I'd like to ask for two things:

1. Could you add required_ruby_version = '>=2.1' (or some later version) to the gemspec and release a 3.2.6 with that change?
2. Could you yank version 3.2.5, so that bundler doesn't try to install it on older rubies?

Thanks a lot, and let me know if there's anything I can help with to make this move faster :)
