[Feature Request] YamlToAttributeSymfonyValidatorRector

[gnutix]

Feature Request

Hello there!

While doing some profiling on my application, I found out a lot of time was spent parsing a YAML file of ~1300 lines that defines Symfony Validator constraints for objects in our legacy folder. I thought it would be better to migrate them to attributes, and searched for a Rector that would do the job. Apparently there's none yet, but Doctrine's YamlToAttributeDoctrineMappingRector seems to do something quite similar.

I was wondering if anyone here would have the knowledge to implement this feature, or help me try to implement it ?
Or should it be a separate script like https://github.com/symplify/config-transformer ?

Hey, I think best way is to copy YamlToAttributeDoctrineMappingRector behavior and adding it's symfony/validator attributes counterbehavior.

The https://github.com/symplify/config-transformer is designed exlusively for YML to PHP 1:1 configs. Not suitable here.
