feature request: add option to skip response validation

[justenwalker]

Description

There should be an option to skip response validation. The response from the actual API is the canonical response.
So when the API gives one, we should be able to receive it. If the response from the API does not validate, there should be an option not to be strict and error, but instead try "best effort".

References

For example, lets say an API says a field is required in the response, but its only available in the response under certain conditions.

I've worked with an API that behaved like this:

1. The Spec says the "users" field is required in the response
2. If the API has users, it returns a "users" property filled out with the users it found

=> | GET /users
<= | {"users:" [ {...}, {...}, {...} ]}

3. However, if there are no users, it returns an empty object:

=> | GET /users
<= | {}

The code generated by ogen check to see if the response contains the "users" property and fails in the second scenario; when in reality I don't actually care. I have no control over the OpenAPI Spec of the API in question, so unless it is fixed upstream I would have to make some manual edits to the spec before generation in order to make it optional and prevent this from erroring out.
