Bundle install error with v19.1

[millenc]

After updating to the v19.1 version, doing bundle install fails with the following error:

Gem::Ext::BuildError: ERROR: Failed to build gem native extension.

An error occurred while installing nkf (0.2.0), and Bundler cannot continue.

In Gemfile:
  cocoapods was resolved to 1.15.2, which depends on
    xcodeproj was resolved to 1.25.0, which depends on
      CFPropertyList was resolved to 3.0.7, which depends on
        nkf

Doing the same on the v19.0 version works properly and all gems are compiled/installed. Somehow the change introduced on v19.1 that downgrades gcc is not working as expected (see release notes):

This minor release restores the gcc version that was used inside v18.0 for backward compatibility.

changes gcc from gcc 13 to gcc-11 by @jabbas in #244

considering the following error on the logs:

make: x86_64-linux-gnu-gcc: No such file or directory

For reference, my Gemfile looks like this:

source 'https://rubygems.org'

# You may use http://rbenv.org/ or https://rvm.io/ to install and use this version
ruby ">= 2.6.10"

# Cocoapods 1.15 introduced a bug which break the build. We will remove the upper
# bound in the template on Cocoapods with next React Native release.
gem 'cocoapods', '=1.15.2'
gem 'activesupport', '=6.1.7.6'
gem "fastlane"

plugins_path = File.join(File.dirname(__FILE__), 'fastlane', 'Pluginfile')
eval_gemfile(plugins_path) if File.exist?(plugins_path)

For now, I've fixed this by pining the image version to v19.0 but a more permanent solution would be appreciated.

I'll be reverting all the recent changes and publish v20.0 as this is breaking react-native CI as well
