Subject: [ruby-core:105876] [Ruby master Feature#18279] ENV.merge! support multile arguments as hash.

Issue #18279 has been reported by zw963 (Wei Zheng).

----------------------------------------
Feature #18279: ENV.merge! support multile arguments as hash.
https://bugs.ruby-lang.org/issues/18279

* Author: zw963 (Wei Zheng)
* Status: Open
* Priority: Normal
----------------------------------------
I give a useful example for this.

```rb
require 'yaml'
env_files = ['config.yml', 'config.local']
envs = env_files.filter_map {|file| YAML.load_file(file)['env'] if File.file?(file) }
ENV.merge!(*envs) # Raise wrong number of arguments (given 2, expected 1)


```
