Advanced Sorbet generic sample

[cretz]

What was changed

• Start including Gemfile.lock files in this repo
• Add sorbet_generic sample
  • Show how to use tapioca to auto generate RBI files
  • Show how to add shims for generics and better type safety
  • Show activity, workflow, signal, query, and update implementations and invocations with Sorbet signatures
  • Document some of the issues encountered when using Sorbet

When reviewing, can ignore everything in the sorbet_generic/sorbet folder.

Do we really want to check in all the generated code? That's a pretty huge amount of stuff to put in there generated.

As far as the actual approach, I guess it works if you're super, super motivated to use this but honestly it seems like it's more obnoxious than it's worth. I trust that there isn't some better way to use Sorbet than what you found, so I think this will mostly serve as documentation that it just isn't really a great option here.

Do we really want to check in all the generated code?

Yes, per https://sorbet.org/docs/adopting#step-6-source-control:

All files generated by tapioca init (including bin/tapioca) should be committed to source control, including the entire sorbet directory. [...] See also this explanation of why we commit RBIs.

This is the primary reason that, unlike other samples, I made this sample be its own project with its own Gemfile, so I wouldn't need all this mess at the top-level.

This is true. I should clarify in the README that this is only for people that want to experiment with advanced generics. For those wanting to use traditional not-really-typed auto-generated Sorbet stuff like any other non-Sorbet Ruby library, they can just do the auto generation and move on, they don't even need this sample. The goal if this sample was to show generics, so I may even rename it to sorbet_generics in addition to that README clarification.
