400 instead of 422

[romkazor]

When pydantic validation failed (post request), automatic 400 raise instead 422.
How can we include 422 default sheme validation in oas or other user schemas?!

Currently is not possible to custom the error status code.
And IMHO if a pydantic validation failed 400 is more appropriate.
If you really want always return a 422 instead of 400, you can monkey patch aiohttp_pydantic.view.inject_params.
I will provide a way to trigger a pydantic validation error and return a custom response.

Done in version 1.10.0 See documentation https://github.com/Maillol/aiohttp-pydantic/#custom-validation-error for details
