Undeprecate plural positional argument

```ruby
pluralize people.count, 'person', 'people'
```
reads more naturally than
```ruby
pluralize people.count, 'person', plural: 'people'
```
so let's not deprecate it.

We could label both, but that's a mouthful:
```ruby
pluralize people.count, singular: 'person', plural: 'people'
```

(The `plural:` kwarg shipped in 5.0.0, so we're keeping it.)
