Task input

🐛 Update `ValidationError` schema to include `input` and `ctx`

## Summary

Related to #10787

The OpenAPI `ValidationError` schema was outdated and didn't reflect the actual error format returned by Pydantic V2.

## Changes
Updated `validation_error_definition` in `fastapi/openapi/utils.py` to include:
- `input`: The actual input value that caused the validation error  
- `ctx`: Optional context dictionary with additional error information

## Testing
All existing tests pass with the updated schema. The test snapshots have been updated to reflect the new schema structure.
