sorbet: Regenerate homegrown RBI files with brew typecheck --update

- I needed to add some more `require`s to the `tty.rb` generator script
  since it failed to recognise `env_config` and Sorbet's `T` setup if I
  ran it not via `brew ruby`, and I couldn't get `brew ruby` to work
  within `safe_system` in the `typecheck` dev-cmd.
