Subject: [ruby-core:84333] [Ruby trunk Feature#14197] `Enumerable#{select, reject}` accept a pattern argument

Issue #14197 has been reported by znz (Kazuhiro NISHIYAMA).

----------------------------------------
Feature #14197: `Enumerable#{select,reject}` accept a pattern argument
https://bugs.ruby-lang.org/issues/14197

* Author: znz (Kazuhiro NISHIYAMA)
* Status: Open
* Priority: Normal
* Assignee: 
* Target version: next minor
----------------------------------------
`#all?`, `#any?`, `#none?`, and `#one?` accept a pattern argument since 2.5.0.
But `#select`, and `#reject` don't.

The features are exist as `#grep`, and `#grep_v`, but there are hard to remember for me when I use `#select`, or `#reject`.

So I want to write

```ruby
collection.reject(/re/)
```

instead of

```ruby
collection.reject {|item| /re/ =~ item }
```

nor

```ruby
collection.grep_v(/re/)
```
