Unused variable warning

honeybadger-5.26.2/lib/honeybadger/backtrace.rb:124: warning: assigned but unused variable - instance

I've seen Honeybadger ship a number of gem versions with unused variable warnings. Do you guys have Ruby warnings logged by default? Would you consider integrating a linter like standard to auto-format and auto-fix minor issues like this? Sidekiq has been using standard for many years and it's been fantastic.

Yup, we'd merge a PR that added Standard and updated the code to pass its checks.
