🚀 New Feature: Engine Updates

Welcome to your first update for the engine or runtime! It tries to change all the places where the version of the engine is configured. We're most likely missing a few of those or handling them incorrectly, so please help us and let us know and we'll quickly add it to the workflow.

If you want to know more about this feature, we just blogged about it.

If you're not interested in engine updates at all, you can reply to this PR with @depfu pause.

@halfbyte @theflow just a quick note - it seems from depfu/feedback#43 that the .travis.yml file should have been updated automatically with this engine update in this PR, but that wasn't the case. If there's any further details I can provide that would be helpful, do let me know! :)

Thanks @pat for letting us know, we didn't handle the all on one-line rvm: 2.7.1, but it's fixed now!

Great to hear, I look forward to the next Ruby release to test it out 😁 Thank you!
