Feature: Re-generate model RBIs on db:migrate

[bmulholland]

It would be nice if the RBIs were auto-updated as a hook when db:migrate is run. Here's an example of how another project does that: https://github.com/ctran/annotate_models/blob/develop/lib/tasks/annotate_models_migrate.rake

I've tried building something like that before. I think it was a bit slow to run as part of db migration. It is an incomplete solution, since it doesn't cover RBI changes when someone update a model.

An alternative is to enforce that generated files don't change in CI. We've done that in our team and it can help making sure gem RBI, model rbi & everything up-to-date before a PR is merged. Have you considered doing something like that instead?

What would a check on CI look like? Re-generate all the RBIs and then see if there are changes?

I have considered the CI check, but I also want something that helps with developer ergonomics; CI checks are too late for that.
