docs: remove references to Ruby Version Management

We now support Ruby versions >= 6.8.10, <= 3.2.0 (react-native#36281).
This reduces some of the noise in our docs by removing error prone steps
on setting up a Ruby Version Manager.

-### Ruby
-
-[Ruby](https://www.ruby-lang.org/en/) is a general-purpose programming language. React Native uses it in some scripts related to iOS dependency management. As every programming language, there are different versions of Ruby that have been developed during the years.
-
-React Native uses a `Gemfile` to make sure that your version of Ruby is aligned with what is needed. Currently, macOS 13.2 is shipped with Ruby 2.6.10, which is the **minimum** version required by React Native. Our suggestion is to install a Ruby version manager and to install the most recent matching version of Ruby in your system.
-
-Some common Ruby version manager are:
-
-- [rbenv](https://github.com/rbenv/rbenv)
-- [RVM](https://rvm.io/)
-- [chruby](https://github.com/postmodern/chruby)
-- [asdf-vm](https://github.com/asdf-vm) with the [asdf-ruby](https://github.com/asdf-vm/asdf-ruby) plugin
-
-To check what is your current version of Ruby, you can run this command:
-
-```
-ruby --version
-```
-
-To use React Native your version of Ruby must meet the requirements defined in the [Gemfile](https://github.com/facebook/react-native/blob/main/Gemfile#L4).
-
-### Ruby's Bundler
-
-Ruby uses the concept of **gems** to handle its own dependencies. You can think of a gem as a package in NPM, a formula in Homebrew or a single pod in Cocoapods.
-
-Ruby's [Bundler](https://bundler.io/) is a Ruby gem that helps managing the Ruby dependencies of your project. We need Ruby to install Cocoapods and using Bundler will make sure that all the dependencies are aligned and that the project works properly.
-
-If you want to learn more about why we need this tool, you can read [this article](https://bundler.io/guides/rationale.html#bundlers-purpose-and-rationale).

 ### Xcode
 
 The easiest way to install Xcode is via the [Mac App Store](https://itunes.apple.com/us/app/xcode/id497799835?mt=12). Installing Xcode will also install the iOS Simulator and all the necessary tools to build your iOS app.
