Can we move .pryrc?

Right now we have this `.pryrc`:


```ruby
Pry.config.print = proc do |output, value, _pry_|
  case value
  when ActiveRecord::Relation
    output.puts "=> #{value.to_s}"
  else
    Pry::ColorPrinter.default(output, value, _pry_)
  end
end
```

Since we're in a Rails project, can we move this into a config file?

(Trying to combat the creeping scourge of files in the root folder.)
