Add support for RSpec when using Open Alternate File

[maclunar]

I envision a dropdown select in the Preferences that allows users to switch between default test and RSpec's spec when determining alternate files.

I've opened a barebones PR here: https://github.com/tommasongr/nova-rails/pull/22 but I'm not sure if it would actually work (no idea how to test it locally). Feel free to expand on it if you think it has potential (alternatively give me some pointers on how I can test and refine it myself).

Hi @maclunar, sorry for the late reply but I was away for vacation and before that a bit busy with work. This is for sure a good idea! I personally don't use rspec but I would like to support it for other users. I'll check you PR and get back to you.

Any movement on this? Happy to pitch in if you're low on time :-)
