[String] Add SpanishInflector support for singular and plural

This PR implement a new Inflector using Spanish (ISO Code = es) implemented in this PR symfony/symfony#58228.

* I sort the list of supported Inflectors to follow some rule (alphabet?)
* I just change invalid test from "it" to "qq" (qq doesn't exist as valid ISO code, but it is italian... don't be evil if anyone want to create the italian inflector 😅 )
