[DX] Monkey-patch Rails' schema dumper to add # frozen_string_literal: true

[davidcornu]

Summary of the problem

1. The majority opinion seems to be that we should keep the # frozen_string_literal: true comment around in db/schema.rb
2. Rails doesn't add it by default so this means wasting brain cycles keeping it there

Describe your changes

Patch the schema logic to add it by default.
