The pluralize text helper uses the Inflector to determine the plural
form. The inflector accepts an optional parameter for the locale,
so we can pass it from the text helper to have locale-aware pluralizations
on the text helpers level.

The pluralize text helper now only accepts 2 positional arguments:
`count` and `singular`. Passing `plural` as a positional argument
is now deprecated.

remove unnecessary forwardable require

`Forwardable` has been used in the past

Extract native getter to attr_reader.

Fix warnings in multiple application tests

The getter is doing nothing more than returning the ivar, so it can be
extracted to an attr_reader.

This is primarily to fix method redefinition warnings in class_attribute
but may be of use in other places where we define singleton methods.

It's been a source of confusion that the lower-level `add_column`
referenced the higher level `column` method for available options.
`column` supports additional functionality like `index: true` that is
not present on `add_column`.

This patch moves common option documentation to `add_column` and only
documents the additional options in `column`.

typo

Ok, this explains why the branch showed as green. We don't run files in
isolation for PRs, only for master. Active Support monkeypatches
`BigDecimal#to_s`, so the generated error message was different
depending on if the file was run in isolation

The error message when asserting `greater_than: BigDecimal.new` will
give an error message based on how BigDecimal displays itself. Big
decimal appears to always use scientific notation. This might not be the
best error message for the general case, but the general case wouldn't
use big decimal for the validation. And if they do, they likely need
this level of precision.

Given that this pull request affects a mutable value, we need to test
for and document the affects on the receiver in this case.

Additionally, this pull request was missing a CHANGELOG entry.

[Rails Guides] clarify `belongs_to_required_by_default` option [ci skip]

Original:
    * `config.active_record.belongs_to_required_by_default` is a boolean
      value and controls whether `belongs_to` association is required by
      default.

Modified version:
    * `config.active_record.belongs_to_required_by_default` is a boolean
      value and controls whether validation error is triggered by
