feat: add ata-validator resolver

[armagandalkiran]

Summary

This PR adds a new resolver for ata-validator, an ultra-fast JSON Schema validator for Node.js.

What is ata-validator?

ata-validator is a high-performance JSON Schema validation library that compiles schemas into optimized JavaScript code at runtime. It supports JSON Schema draft 2020-12, provides AJV-compatible error format (keyword, instancePath, schemaPath, params, message), and offers features like coerceTypes and removeAdditional out of the box.

• npm: https://www.npmjs.com/package/ata-validator
• GitHub: https://github.com/ata-core/ata-validator

What is included

• ataResolver — the resolver function that integrates ata-validator with react-hook-form
• parseErrorSchema — maps ata-validator errors (JSON Pointer instancePath) to react-hook-form field paths (dot notation)
• Support for criteriaMode: "all" via appendErrors
• Support for shouldUseNativeValidation via validateFieldsNatively
• resolverOptions.raw for returning unmodified input values on valid data
• schemaOptions passthrough for ata-validator options (coerceTypes, removeAdditional, allErrors, etc.)
