LanguageValidator case sensitive

[oleg-andreyev]

Symfony version(s) affected

6.1.4

Description

LanguageValidator is case-sensitive, while writing EN, en, DE, de are valid.

How to reproduce

• create field that is validated by \Symfony\Component\Validator\Constraints\Language
• validate object/model with this field, try: EN validation won't pass, try en everything will be okay.

\Symfony\Component\Intl\Languages::getAlpha3Codes is returning keys are lower-case.

Possible Solution

• Add option ignore case and if it's TRUE, normalize case (to match \Symfony\Component\Intl\Languages::getAlpha3Codes)
