Subject: [ruby-core:118826] [Ruby master Bug#20671] Do not show "unused block" warning on `send`

Issue #20671 has been reported by ko1 (Koichi Sasada).

----------------------------------------
Bug #20671: Do not show "unused block" warning on `send`
https://bugs.ruby-lang.org/issues/20671

* Author: ko1 (Koichi Sasada)
* Status: Open
* Backport: 3.1: UNKNOWN, 3.2: UNKNOWN, 3.3: UNKNOWN
----------------------------------------
Let's disable "unused block" warning on `send` because now it is hard to recognize the calling method accepts a block or not for general framework.
Now test/unit has this problem.

```ruby
    require 'test/unit'

    class T < Test::Unit::TestCase
      def setup
      end

      def test_foo = nil
    end

    #=> /home/ko1/ruby/install/master/lib/ruby/gems/3.4.0+0/gems/test-unit-3.6.2/lib/test/unit/fixture.rb:284: warning: the block passed to 'priority_setup' defined at /home/ko1/ruby/install/master/lib/ruby/gems/3.4.0+0/gems/test-unit-3.6.2/lib/test/unit/priority.rb:183 may be ignored

```

Implementation:
https://github.com/ruby/ruby/pull/11349

I think we can revisit it when we provide a way to recognize the calling method may accept a block or not.
But now the relaxed behavior is better I think.
