Fixed #14173: Use new SnipeTranslator to handle pluralized localizations

[uberbrady]

Our locale directories are named things like 'en-US'. But the pluralization code used by Laravel (through Symfony) requires locale names to be in the format en_US. This change introduces a new Translator, SnipeTranslator, which is a tiny set of changes against the built-in one. It additionally adds a SnipeTranslationServiceProvider, which loads up the new Translator.

PR Summary

• Introduction of SnipeTranslationServiceProvider
  A new file under app/Providers/SnipeTranslationServiceProvider.php has been added. This file enhances the Translation Service Provider, allowing it to use a new class called SnipeTranslator.

• Creation of SnipeTranslator Service
  Another new file app/Services/SnipeTranslator.php is also included in this PR. It modifies the 'choice' method to alter the language locale format from 'en-US' to 'en_US', streamlining language localization within the application.

• Configuration Modification
  There are modifications to the config/app.php file. The primary change is the replacement of the pre-existing TranslationServiceProvider with the just-introduced SnipeTranslationServiceProvider. This change should help us handle language localization more efficiency in the system.

Really nice work here - thanks so much! And thanks for the time and the rubber-ducking. This one was a tough one, and I think this solution is the least awful of the eleventy-billion we discussed.
