[ruby-core:108839] [Ruby master Feature#18183] make SecureRandom.choose public

Issue #18183 has been updated by midnight (Sarun R).


In case we really can't agree on the name.  
I reimplement the functionality as an independent class on a GitHub's Gist; without using non-public API and the `send` hack, of course.

https://gist.github.com/midnight-wonderer/8fec1c670bd07f26b9466010842d2421

Usage:
~~~Ruby
code_generator = RandomCode.new(choose_from: ('A'..'Z').to_a)
code_generator.call(10)
~~~

It would be better if the functionality is in the core, though.

This issue https://bugs.ruby-lang.org/issues/10849
added `SecureRandom.alphanumeric` and also the private method choose.
`choose` was kept private because the method name wasn't the best name to represent the behavior.
I think if it was called `random_string` it would be very clear what it does.
I also think it should be aliased to choose as well to allow backwards compatibility for people bypassing the private method with `send` (e.g. https://www.thetopsites.net/article/58611103.shtml)

I'm planning to put together a pull request for this. Please let me know if there are any complications I'm not considering.
