Feature #17333: Enumerable#many?

`Enumerable#many?` method is implemented in ActiveSupport.
https://api.rubyonrails.org/classes/Enumerable.html#method-i-many-3F
However, it's slightly different from Ruby's core methods such as `one?` or `all?`, where they take pattern argument.
I believe these methods should behave the same so that it's easier to guess and learn.

We already have `none?`, `one?`, `any?` and `all?`, which translate into `== 0`, `== 1`, `> 0` and `== self.size`.
`many?` method translates into `> 1`, which is reasonable to exist.
Currently we need to write something this:

```ruby
[1, 2, 3].count(&:odd?).size >= 1
```

With `many?`, we can make it much simpler:

```ruby
[1, 2, 3].many?(&:odd?)
```
