Trying to call Faker::Music::Opera.saint_saens fails

[sjjbirch]

Describe the bug

Calling Faker::Music::Opera.saint_saens will fail with:

...rbenv/versions/3.2.2/lib/ruby/gems/3.2.0/gems/i18n-1.14.1/lib/i18n.rb:394:in `handle_exception': Translation missing: en.faker.opera.french.by_camille_saint_saens (I18n::MissingTranslationData) 

To Reproduce

Call 'Faker::Music::Opera.saint_saens` in Faker 3.2.0

Use the reproduction script below to reproduce the issue:

# frozen_string_literal: true

require "bundler/inline"

gemfile(true) do
  source "https://rubygems.org"

  git_source(:github) { |repo| "https://github.com/#{repo}.git" }

  gem 'faker', :git => 'https://github.com/faker-ruby/faker.git', :branch => 'main'
  gem "minitest"
end

require "minitest/autorun"

class BugTest < Minitest::Test
  def test_faker
    @french_words_are_not_real = Faker::Music::Opera.saint_saens # No need to go further.
  end
end

Expected behavior

Return one of:
- L'ancêtre
- Ascanio
- Les barbares
- Déjanire
- Étienne Marcel
- Frédégonde
- Hélène
- Henry VIII
- Phryné
- La princesse jaune
- Proserpine
- Samson and Delilah
- Le timbre d'argent

Additional context

I think it fails because the spelling in the locale is "by_camille_saint_saëns"
While the spelling in the method is: 'opera.french.by_camille_saint_saens'

According to docs I18n should transliterate ëË to eE by default, but I haven't inspected their code or the call stack and another obvious reason for the failure isn't apparent to me.
