feat(support): add Pluralizer implementation

[innocenzi]

This pull request adds support for pluralizing (or singularizing) nouns through doctrine/inflector. The implementation is a simplified and cleaner version of Laravel's.

This can be used as a helper in application code through LanguageHelpers::pluralize(), but is also intended to be used in the framework itself, such as in database table names, exception and log messages, validation, etc.

Note: I didn't know if I should make a new package or put it in the support one, so I kept things simple and added it to Support. I'm assuming Support will grow over time and it's not a bad place to have it, but at the same time, Clock is a separate package, so I don't know. Happy to update the PR.

Thanks, @innocenzi! This is definitely a good thing to have in the framework, I cannot tell you how many times I have reached for this in Laravel.

What does this implementation do with the words Laravel deems as "uncountable"?

[innocenzi]

Currently, it ignores them because I wanted to keep things simple. I was thinking we could add them back later if needed.

I checked why Laravel had these exceptions and stumbled upon these—it seems they were added a long time ago as an edge case:

• Add uncountable word from Laravel Framework doctrine/inflector#194
• [5.8] Added "Related" and "Recommended" to Pluralizer laravel/framework#28749

I personally think we don't even need to add them, since words like that are quite common and we should instead manually override the table name through the framework.

Agreed. Thank you for the thorough discovery. 🙂
