Latest released gem missing bundler changes

[jcoleman]

3.4.0 is the latest gem version on RubyGems, but it still forcibly requires Bundler 1.x. That changed in 6db5dcd; could you release an updated gem?

An alternative temporary solution is in #138 :

If you see an error message that reads `You must use Bundler 2 or greater with this lockfile.` it means 

* You're using a ruby whose default bundler is version 2 or up; to address this
  * Delete your Gemfile.lock
  * Rebuild it by running `bundle _1.17.3_ install` which uses the version of bundler Transpec depends on
