Add i18n support for Field::HasMany (#2114)
Add i18n support for Field::HasMany (#2114)

If you have ActiveRecord i18n translation of the model you don't need to do
anything extra, if not, make an ActiveRecord i18n translation of the model.

e.g.:

The recipe has many recipe items.

```ruby
ATTRIBUTE_TYPES = {
  recipe_items: Field::HasMany,
  id: Field::Number,
  name: Field::String,
  package_spec: Field::String,
  remark: Field::String,
  created_at: Field::DateTime,
  updated_at: Field::DateTime,
}.freeze
```

```yaml
zh-TW:
  activerecord:
    models:
      recipe: 配方表
      recipe_item: 材料
```
